Thermal slip effect on MHD convective nanofluid flow over a vertical plate embedded in a porous medium

In the present analysis contributions of viscous and Ohmic dissipations on a MHD convective nanofluid flow with thermal slip are studied. Further, the effects of thermal radiation, permeability of the medium in the presence of heat source/sink are also analysed. The numerical solutions to governing equations are obtained applying fourth order Runge-Kutta method with an error tolerance of 10-4. The velocity, temperature, concentration and nanoparticle volume fraction profiles are presented graphically. The surface criteria in respect of shearing stress and rate of heat transfer are also discussed. The validation of the reported results complements to the observations. One striking outcome is to note that the presence of sink causes heat flow from the fluid to bounding surface. This may be ascribed to significant generation of heat due to viscous and Ohmic dissipations in nanofluid flow to override the effect of sink. © 2018 Lavoisier
