International Journal of Exergy (IJEX), Vol. 20, No. 3, 2016

Abstract: In this paper, peristaltic flow of nanofluid in an asymmetric channel is examined. The governing equations of nanofluid model for an asymmetric channel are derived and the coupled differential equations are abridged by employing long wave-length and low Reynolds number postulations. Homotopy perturbation technique is incorporated for analytical solution of reduced system of coupled differential equations. Entropy generation is computed by appraisal of thermal and fluid viscosity contribution. The physical features of relevant parameters have been debated by plotting the graphs of pressure rise, fluid velocity, temperature, concentration, entropy generation number, Bejan number and stream functions.
