Description
Summary:This study is conducted to examine the influence of temperature dependent viscosity on slip flow over a convective sheet. Brownian motion and thermophoresis effects are taken into consideration in the presence of applied magnetic field and Joule heating. The emerging nonlinear problem is presented and tackled numerically using Runge–Kutta Fehlberg method coupled with shooting scheme. Graphical results for velocity, temperature, concentration field and skin friction are obtained and analyzed in a physical manner. Skin friction at the wall enhances with increasing magnetic field parameter. Local heat flux is found to be an increasing function of thermal radiation and Biot number. The model is valid in nano-material industrial developments containing extruding sheets.
