 Abstract

This paper presents the mathematical model for analyzing the nanofluid flow over a vertical porous slender cylinder. Heat and mass transfer characteristics are considered. Flow is driven exclusively by linearly stretching the cylinder and the nanofluid model is of two phase fluid where the nanoparticles move arbitrarily and increase the energy exchange rates therefore consolidating the impacts of Brownian movement and thermophoresis. The governing cylindrical equations are transformed into coupled ordinary differential equations using suitable transformation and are solved numerically via Keller box method. The impact of physical parameters on the velocity, temperature and concentration profiles are presented graphically and analyzed. To validate the numerical method, comparisons are made with the available results in the literature for some special cases and the results are found to be in excellent agreement. The analysis reveals many interesting behaviors that warrant further study on the axi-symmetric flow phenomena especially the nanofluid past a vertical slender cylinder.
