SECOND LAW ANALYSIS OF A PERISTALTIC FLOW OF AN INCOMPRESSIBLE VISCOUS FLUID IN A CURVED CHANNEL
The present investigation extends a consideration of a peristaltic flow in curved channels through the second law analysis. The lubrication approximation is employed to linearize the momentum, energy, and entropy generation rate equations. The stream function and temperature distribution are used to calculate the entropy generation number and the Bejan number. It is shown that the entropy generation rate in a peristaltic pump increases with the occlusion parameter. The entropy generation increases at the upper wall and decreases near the lower wall of the peristaltic channel as the curvature parameter increases. A curved surface acts as a strong source of entropy generation.
