Abstract
In this paper, the effects of viscous dissipation, Joule heating, and magnetic field on the Hiemenz flow of a micropolar incompressible, viscous, electrically conducting fluid impinging normal to a plane are investigated. Numerical solutions for the governing momentum, angular momentum, and energy equations are given. A discussion has been provided for the effects of Hartman number, Prandtl number, Eckert number, and the micropolar parameters on two-dimensional flow of a fluid near a stagnation point (Hiemenz flow). Results for the details of the velocity, angular velocity, and temperature distributions as well as the skin friction, wall couples stress, rate of heat transfer, and thermal boundary layer thickness are shown graphically.
