FREE CONVECTIVE FLOW, HEAT AND MASS TRANSFER IN A MICROPOLAR FLUID OVER A SHRINKING SHEET IN THE PRESENCE OF A HEAT SOURCE

The paper considers a free convective fl ow of a micropolar fl uid in the presence of a heat source/sink over a shrinking sheet. Similarity transformations are used to reduce the governing coupled nonlinear partial differential equations, namely, the momentum and concentration equations, as well as the nonhomogeneous heat equation, to a set of nonlinear ordinary differential equations. Their numerical solution is obtained by the Runge–Kutta fourth-order method accompanied by the shooting technique. The effects of various physical parameters characterizing the fl ow are studied. The validation of the present results by the earlier published ones is performed in a particular case, and good agreement is obtained.
