Model of electrothermal convection of an ideal dielectric in a horizontal capacitor

Resumo

The behavior of a nonuniformly heated dielectric in a variable electric field of a horizontal capacitor is studied. The action of the dielectrophoretic mechanism of instability associated with the temperature dependence of the dielectric permeability is considered. The model of electroconvection of the ideal dielectric is obtained for the boundary conditions corresponding to the no-flow condition on the rigid surface. Nonlinear flow regimes are investigated in the case of microgravity. A map of the regimes is constructed.
