| In this paper a simplified mathematical model is presented to study the flow, heat transfer and entropy generation analysis of Powell-Eyring nanofluid over an infinite horizontal surface. The flow is induced by the nonlinear stretching of the surface and partial slip conditions are assumed at the boundary. The Cattaneo-Christov heat flux model and thermal radiation effects are also considered in the present study. The governing system of partial differential equations are first transformed into a system of ordinary differential equation and then solved numerically using Keller box numerical scheme. Numerical computations are carried out for Copper-water and Titanium oxide-water nanofluids. Moreover five different types of nanoparticle shapes, namely, sphere, hexahedron, tetrahedron, cylinder and lamina are considered. The effect of non-dimensional physical parameters appearing in the system have been observed on the velocity, temperature and entropy profiles along with the velocity gradient and the rate of heat transfer at the boundary |
