Effects of Thermal Radiation and Slip Mechanism on Mixed Convection Flow of Williamson Nanofluid Over an Inclined Stretching Cylinder

Abstract

Abstract The current investigation highlights the mixed convection slip flow and radiative heat transport of uniformly electrically conducting Williamson nanofluid yield by an inclined circular cylinder in the presence of Brownian motion and thermophoresis parameter. A Lorentzian magnetic body force model is employed and magnetic induction effects are neglected. The governing equations are reduced to a system of nonlinear ordinary differential equations with associated boundary conditions by applying scaling group transformations. The reduced nonlinear ordinary differential equations are then solved numerically by Runge-Kutta-Fehlberg fifth-order method with shooting technique. The effects of magnetic field, Prandtl number, mixed convection parameter, buoyancy ratio parameter, Brownian motion parameter, thermophoresis parameter, heat generation/absorption parameter, mass transfer parameter, radiation parameter and Schmidt number on the skin friction coefficient and local Nusselt are analyzed and discussed. It is found that the velocity of the fluid decreases with decrease in curvature parameter, whereas it increases with mixed convection parameter. Further, the local Nusselt number decreases with an increase in the radiation parameter. The numerical comparison is also presented with the existing published results and found that the present results are in excellent agreement which also confirms the validity of the present methodology.
