Radiation effects on laminar boundary layer flow along a stretching cylinder

Abstract

A steady boundary layer flow and heat transfer over a continuously stretching cylinder in the presence of radiation is examined. By similarity transformation, the governing partial differential equations are transformed to nonlinear ordinary differential equations. Numerical solutions are obtained by employing the implicit finite difference of Keller-box scheme. The effects of radiation parameter, curvature parameter and Prandtl number on the heat transfer on the surface were discussed. It can be concluded that as the radiation parameter increases, the heat transfer decreases, while when Prandtl number or temperature exponent increases, the heat transfer at the surface increases. © 2013 AIP Publishing LLC.
