Turbulent Magneto-Convection in a Differentially Heated Enclosure

摘要：

　　Numerically investigation was carried out for turbulent magnetohydrodynamics natural convection in a square enclosure.The vertical walls are maintained isothermal at different temperatures and the horizontal walls are adiabatic.Non linear governing equations for the fluid flow and heat transfer are solved by finite volume method.The computations are carried out for Rayleigh number 107,Hartmann numbers from 0 to 800 and Prandtl number 0.01(sodium).It is observed that as Hartmann number increases the thermal boundary layer near the vertical walls is disappeared and average Nusselt number reduces and mechanism of heat transfer changes from convection to conduction mode.
