Abstract

In the present paper, we have discussed the pipe flow of a Johnson-Segalman fluid with temperature dependent viscosity. The series solutions of coupled nonlinear equations have been obtained for two cases of viscosity (Reynold and Vogels) by homotopy analysis method (HAM). The expressions for velocity, temperature, and entropy generation number have been presented graphically to discuss the physical significance of pertinent parameters of interest. The convergence of the series solution have been discussed by plotting -curves.
