Abstract
In this paper, we analyzed the effects of partial slip on unsteady viscous flow and heat transfer of a nanofluid towards a contracting cylinder with Newtonian heating. The nanofluid model employed in the analysis includes the combined effects of Brownian motion and thermophoresis. Using appropriate similarity variables, the governing nonlinear partial differential equations have been transformed into a set of coupled nonlinear ordinary differential equations, which are solved numerically by an efficient implicit, iterative, finite-difference method. Graphical results for the dimensionless velocity, temperature, and nanoparticle concentration profiles are presented for various values of parameters controlling the flow regime. The expressions for the local skin friction coefficient, reduced Nusselt number, and the reduced Sherwood number are illustrated in tabular form and discussed quantitatively.
