Abstract
This article considers the heat transfer effects in peristaltic flow of a couple stress fluid. An incompressible fluid is considered in a channel under convective boundary conditions. This study is motivated by investigations of physiological flow through particle size effect. The long wavelength and low Reynolds number approach is adopted. Effects of various physical parameters reflecting the couple stress parameter and Brinkman and Biot numbers on the velocity profile, streamlines pattern, temperature profile, pumping action, and trapping are studied. Computational results are presented in a graphical form. It is revealed that pressure rises and axial velocity decreases with increase in the couple stress parameter. The temperature also decreases by increasing the Biot number.
