The influence of two counter-rotating magnetic fields on the hydrodynamic and thermal properties in a cylindrical vessel

Solutions have been found for the isothermal and nonisothermal problems of the motion of an electrically conducting fluid exposed to the effects of two counter-rotating magnetic fields in a cylindrical vessel. The original temperature was used to calculate the distribution of the electromagnetic forces. The method permitted one to consider the finite dimensions of the inductor and vessel containing the fluid, and also to take into account the field generated by the frontal winding parts. It was shown how the velocity and temperature varied as functions of the electromagnetic forces induced by both inductors and of the buoyancy force which provided a thermogravitational convection. It was shown that these forces make it possible to control the hydrodynamic and heat/mass transfer phenomena and that the character of the velocity patterns in a rotating magnetic field greatly depends on the thermogravitational flows.
