INFLUENCE OF THERMAL RADIATION ON NATURAL CONVECTION BOUNDARY LAYER FLOW OF A NANOFLUID PAST A VERTICAL PLATE WITH UNIFORM HEAT FLUX

In this analysis, the boundary layer flow and heat and mass transfer over a vertical plate due to a nanofluid with the effects of thermal radiation and uniform heat flux have been investigated. The transport equations used in the analysis took into account the effect of Brownian motion and thcrmophoresis parameters. Similarity transformation is used to convert the governing non-linear boundary-layer equations into coupled higher order non-linear ordinary differential equations. These equations are numerically solved using fourth order Runge-Kutta method along with shooting technique. An analysis has been carried out to elucidate the effects of governing parameters corresponding to various physical conditions. The dimensionless skin friction increases as the Prandtl number, but decreases as the buoyancy ratio parameter and radiation parameter increases. The reduced Nusselt number increases as the Prandtl number and radiation parameter increase. Comparison with published results is presented.
