Abstract

In this work, analytical study of Hall current and Ion-slip effects on the rate of entropy generation of couple stress fluid is considered. The obtained partial differential equations governing the flow are reduced to ordinary differential equations by similarity variables, semi-analytical solution of the dimensionless nonlinear coupled differential equations for velocity, temperature, entropy generation and Bejan number are constructed using Differential Transform Technique. Effects of Hall current, Ion-slip, couples stress and magnetic parameters are presented and discussed graphically. From the results it is observed that Hall current and rotation parameters enhance secondary velocity, fluid temperature and entropy generation. In addition rarefaction and Hartman number reduce fluid temperature and entropy generation.
