Abstract
The article presents a numerical study performed on analysis of unsteady magneto-convective heat transfer in a square enclosure with partial active wall. The thermally insulated top and bottom wall while the left vertical wall is heated at Centre the rest of the left vertical wall is adiabatic and right vertical wall maintained at a lower temperature T c. MAC (Marker-and-Cell) method is used to solve numerically set of dimensionless governing partial differential equations. The effect of local heat source on left wall is evaluated. The influence of the governing of thermophysical parameters, namely Prandtl number, Rayleigh number \(\left( {Ra} \right)\), Hartmann number \(\left( {Ha} \right)\), Grashof number \(\left( {Gr} \right)\) and Reynolds number \(\left( {Re} \right)\), is obtained. The results of streamlines and temperature are presented graphically and discussed.
