Presence of heat generation/absorption on Boundary layer slip flow of nanofluid over a porous stretching sheet

Abstract

In our present study, the boundary layer flow of nanofluid over a porous stretching sheet due to presence of heat generation/absorption with effects of velocity slip condition and convective boundary condition using homotopy analysis method have been investigated. The fluid flow and heat transfer equations used for the analysis take care on the influence of suction and blowing parameter the permeability parameter of porous medium, Velocity slip parameter, convective Biot number, Heat generation/absorption parameter, Prandtl number, Brownian motion parameter, Thermophoresis parameter, and Lewis number. The solution for the velocity, temperature, and concentration of nanoparticle depends on parameters are analysis numerically and graphically. The governing equations which are non-linear boundary-layer equations are be transformed to couple of higher order non-linear ordinary differential equations using similarity transformation. This system is solved analytically using homotopy analysis method. An investigation has been carried out to show the influence of involved parameters corresponding to several physical conditions. Numeral data are obtained for profiles of velocity, temperature, and nanoparticle concentration for different values of involved parameters. A comparative analysis with previous studies published found in the literature and present results in a limiting case are found to be in excellent agreement.
