Thermomagnetic convection in a differentially heated rotating annulus with central force field

Abstract

Thermal convection is induced in a rotating differentially heated annulus by using a central magnetic force field. The principle of the system is used to simulate large scale convection such as that found in planetary interiors or atmospheres but in a laboratory scaled model to investigated geophysical flow fields. Results suggest that magnetic fluids can be used to study such phenomena in a microgravity environment. To quantify the thermal forcing, rotational forcing and stratification several non‐dimensional parameters are introduced to characterise the evolving thermal structures.

Thermo‐electrohydrodynamic convection in the thermally driven spherical shell with differential rotation

“…The major application of TEHD convection is to enhance heat transfer and to study its convective nature compared to fee convection. However, there are other areas of interest such as the possibility of creating convection with a central force field [12][13][14][15][16]. This enables to study spherical shell convection to investigate convective flow in planetary interiors or atmospheres.…”
