• THE INFLUENCE OF THERMAL RADIATION ON THE CONVECTIVE FLOW PAST A VERTICAL RADIALLY STRETCHING SHEET IN THE PRESENCE OF A HEAT SOURCE

Abstract

A boundary layer flow analysis is performed to study the influence of thermal radiation and heat source on the flow of an incompressible viscous fluid over a vertical radially stretching sheet. The governing system of partial differential equations is first transformed into an ordinary differential equations using similarity transformations and then the transformed boundary layer equations are solved numerically. The present results are compared with the available published results and it is found that the results are in excellent agreement. The salient features of the flow, heat transfer characteristics for different values of thermal radiation, thermal conductivity and intensity of heat generation are discussed. The influence of the physical parameters on the coefficients skin friction, local Nusselt number are calculated and discussed. It is observed that increase in values of the radiation parameter increase the skin friction and Nusselt number, while the increase in the Prandtl number decreases the skin friction and Nusselt number.
