Heat Transfer Flow of Steady Couple Stress Fluids between Two Parallel Plates with Variable Viscosity

摘要

In this paper, we study the nonisothermal flow of couple stress fluids between two heated parallel plates for a Reynolds viscosity model. Depending on the relative motion of the plates, we consider four different problems, namely, the plane Couette flow, plug flow, plane Poiseuille flow, and generalized plane Couette flow. Approximate analytical expressions for velocity and temperature distribution are obtained by using the perturbation technique. The influence of different parameters on the flow pattern has been discussed and presented with the help of graphs.
