Boundary Layer Flow past a Stretching Cylinder and Heat Transfer with Variable Thermal Conductivity

Abstract

In the present paper, the boundary layer flow of viscous incompressible fluid over a stretching plate has been considered to solve heat flow problem with variable thermal conductivity. First, using similarity transformation, the components of velocity have been obtained. Then, the heat flow problem has been considered in two ways: (i) prescribed surface temperature (PST), and (ii) prescribed stretching plate heat flux (PHF) in case of variable thermal conductivity. Due to variable thermal conductivity, temperature profile has its two part-one mean temperature and other temperature profile induced due to variable thermal conductivity. The related results have been discussed with the help of graphs. © 2009 Elsevier Ltd. All rights reserved.
