Abstract In present paper boundary layer flow of Sisko fluid by stretching sheet is examined. Combined effects of nonlinear thermal radiation, heat generation/absorption, Joule heating are discussed. The main purpose is to analyze the entropy generation in Sisko fluid flow. By using suitable similarity variables modeled boundary layer PDE's are transfigured into ODE's. The obtained system of equations are solved by using analytical technique (HAM). Graphs are developed to show the effects of pertinent parameters on velocity, temperature, entropy generation, Bejan number, skin friction and Nusselt number. Velocity for larger material parameter reduces. Temperature is more for greater Biot number and radiation parameter. Bejan number is maximum away from the sheet for shear thickening fluids and approaches to zero for shear thinning fluids.
