Numerical analysis of electromagnetic parameters of thermal dominated double diffusive magneto-convection

摘要

In this study, electromagnetic parameters of MHD thermosolutal natural convection in a cubic cavity were investigated numerically. Vertical boundaries were isothermal at different constant temperature and submitted to different concentrations other boundaries were adiabatic. A uniform magnetic field is imposed in the x-direction. Three-dimensional equations of mass conservation, momentum, energy, species, Ohms law and conservation of electric charge were solved using finite volume method. Results in term of current density, electrical potential, velocity field and Hartmann layer, were obtained for Ra=10 5 , Pr=10, Le=10, N=-0.5 and different Hartmann numbers.
