Abstract: | The present paper deals with the study of heat transfer characteristics in the laminar boundary layer flow of an incompressible
viscous fluid over an unsteady stretching sheet which is placed in a porous medium in the presence of viscous dissipation
and internal absorption or generation. Similarity transformations are used to convert the governing time dependent nonlinear
boundary layer equations into a system of non-linear ordinary differential equations containing Prandtl number, Eckert number,
heat source/sink parameter, porous parameter and unsteadiness parameter with appropriate boundary conditions. These equations
are solved numerically by applying shooting method using Runge-Kutta-Fehlberg method. Comparison of numerical results is made
with the earlier published results under limiting cases. The effects of the parameters which determine the velocity and temperature
fields are discussed in detail. |
