Entropy Analysis of Pressure Driven Flow in a Curved Duct

This paper aims to present a theoretical model describing entropy generation analysis using second law of thermodynamics. A two-dimensional, incompressible, viscous MHD fluid flow in a curved duct undergoing peristalsis with prescribed wall motions in the presence of heat transfer is applied and demonstrated. In this problem, It is assumed that the inertial effect is very small and the wall wave length is comparatively large with duct width. The velocity and temperature fields are obtained analytically by solving momentum and energy equations. The entropy generation number is calculated by utilizing velocity and temperature profiles. The influence of various physical parameters on entropy generation are discussed numerically with the help of graphs.
