ABSTRACT

A boundary layer analysis is presented for studying the effects of heat transfer and transverse magnetic field on Hiemenz flow of a micropolar incompressible, viscous, electrically conducting fluid impinging normal to a plate. Numerical solutions for the governing momentum, angular momentum and energy equations are given. A discussion has been provided for the effect of Hartman number, Prandtl number and micropolar parameters on Hiemenz flow (two-dimensional flow of a fluid near a stagnation point). Results for the details of the velocity, angular velocity and temperature distributions as well as the skin friction, wall couples stress and the rate of heat transfer are shown graphically.
