[BibTeX] [Abstract] [Download PDF]Abstract Thermo-electrohydrodynamic convection is investigated in a shell with central force field to investigate convective pattern formation for potential heat transfer application and small scaled laboratory experiments e.g. the modelling of convection in planetary interiors or atmospheres. To induce TEHD convection the outer and inner shells are heated at different temperatures whereas an alternating electric potential is applied between both shells. The observation of the convective pattern formation suggest that dielectric fluids have a significant response to thermal and electrical forcing. The observed patterns ranged from quasi-stationary convective modes in azimuthal direction to shape and mode amplitude vacillations with mode merging and separation that are classified into three regimes. The heat transfer was evaluated by the Nusselt number and showed an increase in heat transfer with electric forcing. However, the results indicate a much smaller heat transfer when compared to natural convection.

To investigate this particular temperature and flow pattern the Wollaston shearing interferometry is utilised which serves as the measurement system for the AtmoFlow project, a spherical shell that is designed to investigate atmospheric flow fields on the ISS planned to be launched in 2024. To be able to understand the measured flow fields in the sphere, ground experiments are carried out with the differentially heated annulus. For the sake of simplicity, the system is categorised in three classes, the initial isothermal state where only artificial fringes are measured, the conduction case with symmetric fringes and the convective state where fringes align with the crescent shaped convection pattern.

[BibTeX] [Abstract] [Download PDF]The main objective of the AtmoFlow experiment is the investigation of convective flows in the spherical gap geometry. Gaining fundamental knowledge on the origin and behavior of flow phenomena such as global cells and planetary waves is interesting not only from a meteorological perspective. Understanding the interaction between atmospheric circulation and a planet’s climate, be it Earth, Mars, Jupiter, or a distant exoplanet, contributes to various fields of research such as astrophysics, geophysics, fluid physics, and climatology. AtmoFlow aims to observe flows in a thin spherical gap that are subjected to a central force-field. The Earth’s own gravitational field interferes with a simulated central force-field with the given parameters of the model which makes microgravity conditions of g<10−3g0{\$}{$\backslash$}mathrm {\{}g{\}}<10\^{}{\{}-3{\}} {$\backslash$}mathrm {\{}g{\}}{_}{\{}0{\}}{\$}(e.g. on the ISS) necessary. Without losing its overall view on the complex physics, circulation in planetary atmospheres can be reduced to a simple model of a central gravitational field, the incoming and outgoing energy (e.g. radiation) and rotational effects. This strongly simplified assumption makes it possible to break some generic cases down to test models which can be investigated by laboratory experiments and numerical simulations. Varying rotational rates and temperature boundary conditions represent different types of planets. This is a very basic approach, but various open questions regarding local pattern formation or global planetary cells can be investigated with that setup. A concept has been defined for developing a payload that could be installed and utilized on-board the International Space Station (ISS). This concept is based on the microgravity experiment GeoFlow, which has been conducted successfully between 2008 and 2016 on the ISS. This paper addresses the scientific goals, the experimental setup, the concept for implementation of the AtmoFlow experiment on the ISS and first numerical results.

[BibTeX] [Abstract] [Download PDF]We present a numerical study of double-diffusive convection characterized by a stratification unstable to thermal convection, while at the same time a mean molecular weight (or solute concentration) difference between top and bottom counteracts this instability. Convective zones can form in this case either by the stratification being locally unstable to the combined action of both temperature and solute gradients or by another process, the oscillatory double-diffusive convective instability, which is triggered by the faster molecular diffusivity of heat in comparison with that one of the solute. We discuss successive layer formation for this problem in the case of an instantaneously heated bottom (plate) which forms a first layer with an interface that becomes temporarily unstable and triggers the formation of further, secondary layers. We consider both the case of a Prandtl number typical for water (oceanographic scenario) and of a low Prandtl number (giant planet scenario). We discuss the impact of a Couette like shear on the flow and in particular on layer formation for different shear rates. Additional layers form due to the oscillatory double-diffusive convective instability, as is observed for some cases. We also test the physical model underlying our numerical experiments by recovering experimental results of layer formation obtained in laboratory setups.

[BibTeX] [Abstract] [Download PDF]A non-conservative Lagrangian is used to derive a dynamic beam equation in a moving reference frame to describe the motility of Listeria monocytogenes. Bending, stretching, and frictional forces are incorporated to describe the kinematics of the moving actin filament network. Adapted boundary conditions are able to simulate the influence of the bacterium on the tail as well as the polymerization process. A semi-implicit numerical operator splitting method has been developed to solve the nonlinear equations in the plane. The model has been validated on existing force-velocity relationships and measurements for realistic physical model parameters. In particular, the fictional losses due to substrate-tail adhesion have been analyzed by a linear and a nonlinear approach. Numerical simulations are performed for varying polymerization speeds, friction, and bending parameters. Complex trajectories of the actin tail are found by adjusting the bending properties of the attaching actin filament cluster. The results reveal that the present model is able to predict and reproduce actin-based motions observed in experiments.

[BibTeX] [Abstract]Ziele des Vorhabens sind die Verbesserung der Messtechnik für tribologische Untersuchungen in der Kolbengruppe aus dem Vorläufervorhaben Kolbenring-Öltransport I und die Untersuchung von verschiedenen Betriebsbedingungen und Komponenten hinsichtlich ihres Einflusses auf den Ölhaushalt. Der Fokus liegt auf der verbesserten Auflösung der Schmierfilmdickenmessung und der Ringsto√ülagen. Mit der erweiterten Kapillar- und Lichtleiterkonfiguration werden neue Öltransportvorgänge entlang des Kolbenringpakets mittels Tracerinjektion und simultaner LiF-Messung beobachtet. Das methodische Vorgehen bei der optischen Analyse des Kapillarfüllungsgrades wird an einem Labor-Druckprüfstand weiterentwickelt. Des Weiteren werden komplexe Simulationsmodelle erstellt, mit denen die Kolbensekundär-bewegung, die Kolbenringbewegung, die Gasströmung im Ringpaket und der Öltransport im Ringpaket geklärt werden können. Die Kolbensekundärbewegungsrechnung basiert auf einer FEM-Diskretisierung die aus CAD-Modellen sämtlicher Bauteile abgeleitet ist. Die dreidimensionale Berechnung der Kolbenringbewegung erfolgt unter Berücksichtigung dynamisch wirkender Kräfte aus der Bewegung, der Ringreibung, dem Gasdruck und den Zwischenring- drücken. Die Elastizität der Ringe wird berücksichtigt, so dass Biegung, Torsion und damit auch das Twisten abgebildet werden können. Nut- und Ringgeometrie sowie thermisch bedingte Verzüge flie√üen ebenfalls in die Berechnung mit ein.

Der Fokus liegt auf der verbesserten Aufl{\"o}sung der Schmierfilmdickenmessung und der Ringsto√{\"u}lagen. Mit der erweiterten Kapillar- und Lichtleiterkonfiguration werden neue {\"O}ltransportvorg{\"a}nge entlang des Kolbenringpakets mittels Tracerinjektion und simultaner LiF-Messung beobachtet. Das methodische Vorgehen bei der optischen Analyse des Kapillarf{\"u}llungsgrades wird an einem Labor-Druckpr{\"u}fstand weiterentwickelt. Des Weiteren werden komplexe Simulationsmodelle erstellt, mit denen die Kolbensekund{\"a}r-bewegung, die Kolbenringbewegung, die Gasstr{\"o}mung im Ringpaket und der {\"O}ltransport im Ringpaket gekl{\"a}rt werden k{\"o}nnen. Die Kolbensekund{\"a}rbewegungsrechnung basiert auf einer FEM-Diskretisierung die aus CAD-Modellen s{\"a}mtlicher Bauteile abgeleitet ist. Die dreidimensionale Berechnung der Kolbenringbewegung erfolgt unter Ber{\"u}cksichtigung dynamisch wirkender Kr{\"a}fte aus der Bewegung, der Ringreibung, dem Gasdruck und den Zwischenring- dr{\"u}cken. Die Elastizit{\"a}t der Ringe wird ber{\"u}cksichtigt, so dass Biegung, Torsion und damit auch das Twisten abgebildet werden k{\"o}nnen. Nut- und Ringgeometrie sowie thermisch bedingte Verz{\"u}ge flie√{\"u}en ebenfalls in die Berechnung mit ein. Als Ergebnisgr{\"o}√{\"u}en stehen neben den Ringbewegungen und -lagen auch die Gasstr{\"o}mungen und -dr{\"u}cke, Schmierfilmh{\"o}hen und Verlustleistungen zur Verf{\"u}gung.}, address = {Frankfurt am Main}, author = {Uhlig, Benedict and Kirner, Claus and Preuss, Ann-Christin and Graf, Johann and Neben, Matthias and Zaussinger, Florian}, date-added = {2018-07-31 17:12:15 +0200}, date-modified = {2019-08-29 07:25:06 +0200}, keywords = {zaussinger}, language = {de}, pages = {70}, publisher = {FVV, Forschungsvereinigung Verbrennungskraftmaschinen}, title = {{Kolbenring-{\"O}ltransport II : {\"O}ltransport durch die Kolbenringe}}, year = {2018}}

[BibTeX] [Abstract] [Download PDF]Semi-convective mixing, as an example of double-diffusive convection, is of general importance in multi-component fluid mixing processes. In astrophysics it occurs when the mean molecular weight gradient caused by a mixture of light material on top of heavier one counteracts the convective instability caused by a temperature gradient. Direct numerical simulations of double-diffusive fluid flows in a realistic stellar or planetary parameter space are currently non-feasible. Hence, a model describing incompressible semi-convection was developed, which allows to investigate semi-convective layer formation. A detailed parameter study with varying Rayleigh number and stability parameter has been performed for the giant planet case. We conclude that semi-convective layering may not play that important role as suggested in earlier works for the planetary case.

Even though we greatly benefit from the high accuracy of our fifth order numerical scheme (WENO5) the broader stencils needed for the numerical scheme complicate the implementation of boundary conditions. We show that the effective temperature of a numerical simulation cannot be changed by corrections at the lower boundary since the thermal stratification does only change on the Kelvin–Helmholtz time scale. Except for very shallow models this time scale cannot be covered by multidimensional simulations due to the enormous computational requirements. We demonstrate to what extent numerical simulations of stellar surface convection are sensitive to the initial conditions and the boundary conditions. An ill-conceived choice of parameters for the boundary conditions can have a severe impact. Numerical simulations of stellar surface convection will only be (physically) meaningful and realistic if the initial model, the extent and position of the simulation box and the parameters from the boundary conditions are chosen adequately.

[BibTeX] [Download PDF]@article{Futterer_2013, abstractnote = {AbstractWe introduce, in spherical geometry, experiments on electro-hydrodynamic driven Rayleigh--B{\'e}nard convection that have been performed for both temperature-independent (``GeoFlow I'') and temperature-dependent fluid viscosity properties (``GeoFlow II'') with a measured viscosity contrast up to 1.5. To set up a self-gravitating force field, we use a high-voltage potential between the inner and outer boundaries and a dielectric insulating liquid; the experiments were performed under microgravity conditions on the International Space Station. We further run numerical simulations in three-dimensional spherical geometry to reproduce the results obtained in the ``GeoFlow'' experiments. We use Wollaston prism shearing interferometry for flow visualization -- an optical method producing fringe pattern images. The flow patterns differ between our two experiments. In ``GeoFlow I'', we see a sheet-like thermal flow. In this case convection patterns have been successfully reproduced by three-dimensional numerical simulations using two different and independently developed codes. In contrast, in ``GeoFlow II'', we obtain plume-like structures. Interestingly, numerical simulations do not yield this type of solution for the low viscosity contrast realized in the experiment. However, using a viscosity contrast of two orders of magnitude or higher, we can reproduce the patterns obtained in the ``GeoFlow II'' experiment, from which we conclude that nonlinear effects shift the effective viscosity ratio.}, author = {Futterer, B. and Krebs, A. and Plesa, A.-C. and Zaussinger, F. and Hollerbach, R. and Breuer, D. and Egbers, C.}, date-added = {2017-01-12 14:56:54 +0000}, date-modified = {2019-03-14 19:52:55 +0100}, doi = {10.1017/jfm.2013.507}, journal = {Journal of {F}luid {M}echanics}, keywords = {GEOFLOW,zaussinger}, month = {Nov}, pages = {647--683}, place = {Cambridge, UK}, publisher = {Cambridge University Press}, title = {Sheet-like and plume-like thermal flow in a spherical convection experiment performed under microgravity}, url = {https://www.cambridge.org/core/article/div-class-title-sheet-like-and-plume-like-thermal-flow-in-a-spherical-convection-experiment-performed-under-microgravity-div/32CFFF7061E5F96C8153453826DCFF55}, volume = {735}, year = {2013}, bdsk-file-1 = {YnBsaXN0MDDSAQIDBFxyZWxhdGl2ZVBhdGhYYm9va21hcmtfEBtQYXBlcnMvMjAxM19KRk1fR2VvRmxvdy5wZGZPEQM4Ym9vazgDAAAAAAQQMAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAANAIAAAUAAAABAQAAVXNlcnMAAAAFAAAAAQEAAGR1Y2t1AAAACQAAAAEBAABEb2N1bWVudHMAAAAHAAAAAQEAAEJpYkRlc2sABgAAAAEBAABQYXBlcnMAABQAAAABAQAAMjAxM19KRk1fR2VvRmxvdy5wZGYYAAAAAQYAAAQAAAAUAAAAJAAAADgAAABIAAAAWAAAAAgAAAAEAwAAr0EAAAAAAAAIAAAABAMAACldBQAAAAAACAAAAAQDAAAMAwYAAAAAAAgAAAAEAwAANhEGAAAAAAAIAAAABAMAADoRBgAAAAAACAAAAAQDAADBEQYAAAAAABgAAAABBgAAlAAAAKQAAAC0AAAAxAAAANQAAADkAAAACAAAAAAEAABBvt238QAAABgAAAABAgAAAQAAAAAAAAAPAAAAAAAAAAAAAAAAAAAACAAAAAQDAAAEAAAAAAAAAAQAAAADAwAA9gEAAAgAAAABCQAAZmlsZTovLy8MAAAAAQEAAE1hY2ludG9zaCBIRAgAAAAEAwAAAJCClucAAAAIAAAAAAQAAEHGc4ZhgAAAJAAAAAEBAABERThBOTNEMi1BMEU2LTQyN0UtQTJGNS0zM0M3Q0U1RUFGQkMYAAAAAQIAAIEAAAABAAAA7xMAAAEAAAAAAAAAAAAAAAEAAAABAQAALwAAAAAAAAABBQAAGgAAAAEBAABOU1VSTERvY3VtZW50SWRlbnRpZmllcktleQAABAAAAAMDAADlCgAAzAAAAP7///8BAAAAAAAAABAAAAAEEAAAdAAAAAAAAAAFEAAA9AAAAAAAAAAQEAAAJAEAAAAAAABAEAAAFAEAAAAAAAACIAAA8AEAAAAAAAAFIAAAYAEAAAAAAAAQIAAAcAEAAAAAAAARIAAApAEAAAAAAAASIAAAhAEAAAAAAAATIAAAlAEAAAAAAAAgIAAA0AEAAAAAAAAwIAAA/AEAAAAAAAABwAAARAEAAAAAAAARwAAAFAAAAAAAAAASwAAAVAEAAAAAAAAEAgCAKAIAAAAAAAAACAANABoAIwBBAAAAAAAAAgEAAAAAAAAABQAAAAAAAAAAAAAAAAAAA30=}} - B.

[BibTeX] [Abstract] [Download PDF]Abstract We investigate the properties of dissipative full discretizations for the equations of motion associated with models of flow and radiative transport inside stars. We derive dissipative space discretizations and demonstrate that together with specially adapted total-variation-diminishing (TVD) or strongly stable Runge-Kutta time discretizations with adaptive step-size control this yields reliable and efficient integrators for the underlying high-dimensional nonlinear evolution equations. For the most general problem class, fully implicit SDIRK methods are demonstrated to be competitive when compared to popular explicit Runge-Kutta schemes as the additional effort for the solution of the associated nonlinear equations is compensated by the larger step-sizes admissible for strong stability and dissipativity. For the parameter regime associated with semiconvection we can use partitioned IMEX Runge-Kutta schemes, where the solution of the implicit part can be reduced to the solution of an elliptic problem. This yields a significant gain in performance as compared to either fully implicit or explicit time integrators. ({\copyright} 2011 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
