Computational Study of Mixed Convection Flow with Algebraic Decay of Mainstream Velocity in the Presence of Applied Magnetic Field

Muhammad Ashraf, Uzma Ahmad, Masud Ahmad and Sultana N

The present study concern with the two dimensional viscous, incompressible, electrically con ducting, mixed convection flows with algebraic decay of mainstream velocity U(x)=(1-x)-a. The physical phenomenon of the problem is simulated by using the Primitive Variable Formulation (PVF) for Finite Difference Method (FDM) and Stream Function Formulation (SFF) for Local Non-Similarity Method (LNS). The physical behaviors of momentum and temperature fields are given graphically. The results obtained for skin friction and rate of heat transfer for different values of physical parameters are also compared by both methods and presented in tabular form.
