Variable Fluid Properties and Partial Slip Effect of MHD Flow of Nanofluids over a permeable Stretching Sheet with Heat Radiation and Viscous Dissipation

Abstract

The simultaneous effects of variable fluid properties and velocity slip on a nanofluid flow over a continuously stretching
semi-infinite horizontal sheet are investigated. The contribution of thermal radiation term is taken into account in the temperature
equation. Viscous dissipation, Brownian motion and thermophoresis effects are taking into account. The flow is subjected to a
transverse uniform magnetic field. Thermal conductivity and fluid viscosity are assumed to related linearly and inversely linear with
temperature, respectively. The system of equations governed the problem is transformed into a dimensionless system of ordinary
differential equations. This system is solved using shooting technique in conjunction with Rung-Kuta method. Convergence of the
obtained solutions is examined. It is found that the velocity improved due to increasing θr, whereas increasing tv yields to decrease the
velocity. Increasing volume fraction parameter ϕ and nanolayer thickness tv tend to reduce the temperature. We discuss in detail the
effect of involved parameters on the velocity, temperature, and concentration profiles. In addition, we provide discussions and
tabulated data on skin friction, Nusselt number, and Sherwood numbers.
