ON THE FLOW AND THERMAL CHARACTERISTICS OF MAGNETOHYDRODYNAMIC MICROPOLAR FLUID IN A CHANNEL WITH EXPANDING OR CONTRACTING WALLS
ABSTRAKT
We present the numerical study of thermal characteristics of an unsteady hydromagnetic flow of an incompressible and electrically conducting micropolar fluid in a porous channel with expanding or contracting walls. Different from the classical shooting methodology, we employ a combination of a direct and an iterative method for solving the sparse system of algebraic equations arising from the finite difference discretization of the linearized self-similar nonlinear ODEs. Effects of the governing parameters on the flow and heat transfer characteristics of the problem are discussed and presented through tables and graphs.
