Abstract :
Natural Convection in a rectangular enclosure having internal energy sources and electrically conducting fluid with sinusoidal temperature at the bottom wall has been investigated. The left wall is kept at constant hot temperature but the right wall is at uniform cold temperature. The top wall is adiabatic. The governing partial differential equations are solved by applying weighted residual finite element method. The effects of Hartmann number and internal Rayleigh number on isotherms and streamlines are presented. Also heat transfer from the walls of the cavity is shown graphically. The numerical result demonstrates that the increment of Hartmann number decreases convective heat transmission rate
