Thermo?electrohydrodynamic convection in a differentially heated shell with electric central force field

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 planetary interiors or atmospheres. To induce TEHD outer inner shells are heated at different temperatures whereas an alternating electric applied between both shells. The observation suggest that dielectric fluids have significant response thermal electrical forcing. observed patterns ranged from quasi-stationary modes azimuthal direction shape mode amplitude vacillations merging separation classified into three regimes. was evaluated by Nusselt number showed increase However, results indicate much smaller when compared natural convection.
