Abstract

This study was conducted to investigate unsteady natural convection flow of heat generating fluid in a porous vertical channel with velocity slip and temperature jump in the presence of thermal radiation. The governing equations of fluid flow and heat transfer were separated into steady and periodic parts. Exact solutions were obtained for velocity, temperature, skin friction and rate of heat transfer. The effects of radiation and other fluid parameters involved in the fluid flow were highlighted and discussed.
