Effects of Inclined Magnetic Field on Entropy Generation in Nanofluid Over a Stretching Sheet with Partial Slip and Nonlinear Thermal Radiation

The effects of inclined magnetic field on entropy generation in nanofluid over a stretching sheet were investigated in the presence of partial slip and nonlinear thermal radiation. Applying a similarity variable, the governing equations are reduced to a set of nonlinear ODEs. These equations are solved both analytically and numerically by hypergeometric function and Runge-Kutta Gill method with shooting technique, respectively. For Ag-water, magnetic, aligned angle, nanosolid volume fraction and slip parameters on velocity, temperature, skin friction coefficient and reduced Nusselt number were analyzed. The entropy generation for the influence of the same parameters, radiation parameter and the Reynolds number is discussed for Ag nanoparticles. It is observed that the nanosolid volume fraction and slip parameter reduce the entropy generation. But aligned magnetic field enhances the entropy generation.
