A semi analytical study on entropy generation of Eyring-Powell fluid flow through a Microchannel

Abstract

This paper communicates with the entropy generation analysis of Eyring Powell fluid flow through a microchannel in the thermal heat source coefficients. The dimensionless equations of the physical features along with the boundary conditions which are solved by using Homotopy analysis method. An expression of dimensionless velocity and dimensionless temperature are used to determination of the entropy generation number and bejan number explicitly. By using the analytical expression the thermal performances can be improved through the effects of magnetic field, viscous heating, joule heating and convective condition, futhermore it is explaining with graphically.
