Abstract
The present article is a theoretical attempt to investigate the stretching flow and heat transfer phenomena most encountered in plastic films and sheet industry. This study is performed to analyze the behavior of slip flow of ferrofluid in the porous medium. Effects of viscous dissipation and thermal radiation are taken into account in the presence of magnetic dipole. The developed nonlinear ordinary differential equations are tackled numerically using Runge-Kutta Fehlberg method coupled with shooting scheme. Graphical results for velocity, temperature, and skin friction and heat flux are obtained and analyzed in a physical manner. Skin friction at the wall enhances with increasing ferromagnetic- hydrodynamic interaction parameter. Local heat flux is found to be an increasing function of thermal radiation and decreases for increasing ferromagnetic parameter.
