Abstract
Hydromagnetic flow between two horizontal plates in a rotating system, where the lower plate is a stretching sheet and the upper is a porous solid plate, is analyzed. Heat transfer in an electrically conducting fluid bonded by two parallel plates is studied in the presence of viscous dissipation. The equations of conservation of mass and momentum and energy are reduced to a nonlinear ordinary differential equations system. Homotopy perturbation method is used to get complete analytic solution for velocity and temperature profiles. Results show an acceptable agreement between this method results and numerical solution. Also the effects of different parameters are discussed through graphs.

Flow of a viscose fluid over a stretching surface has important applications in polymer industries
A number of technical processes concerning polymers involve the cooling of continuous strips extruded from a die by drawing them through a quiescent fluid with controlled cooling system, and in the process of drawing, these strips are sometimes stretched
Continuous casting of metals, and spinning of fibers involve the flow over a stretching surface
Summary
Flow of a viscose fluid over a stretching surface has important applications in polymer industries. A number of technical processes concerning polymers involve the cooling of continuous strips extruded from a die by drawing them through a quiescent fluid with controlled cooling system, and in the process of drawing, these strips are sometimes stretched. Continuous casting of metals, and spinning of fibers involve the flow over a stretching surface. In all these cases, the quality of the final product depends on the rate of heat transfer on the stretching surface. Dutta et al 1 studied the temperature field in the flow over a stretching surface subjected to uniform heat flux. Andersson et al 2 investigated the unsteady two-dimensional non-Newtonian flow of a power-law fluid past a stretching surface
