Effectiveness of entropy generation and energy transfer on peristaltic flow of Jeffrey material with Darcy resistance

Abstract The primary goal of present article is to analyze the entropy generation on peristaltic flow of Jeffrey material in a curved configuration. Velocity and thermal slip conditions are invoked. An incompressible fluid in a channel saturates the porous space. Modelling is based upon modified Darcy’s law for Jeffrey fluid. Large wavelength and low Reynolds number approximations are utilized. Exact solutions of the resulting system of differential equations with corresponding boundary conditions are computed. Further analysis is made for the pressure gradient, stream function, velocity of the fluid, temperature, entropy generation and Bejan number. It is found that entropy generation and Bejan number are more visible in the vicinity of the channel walls when compared at the channel center.
