A. and Takhar, H. S.¹. Soundalgekar, V. M. and Takhar, H. S. considered semi-infinite vertical plate and studied the Radiation effects on free convection flow². Similar problems were also studied by other researchers³,¹². Our aim is to study radiation effects on impulsively started infinite vertical porous plate in the presence of variable temperature. The temperature of plate is made to rise linearly with time. The fluid of our flow model is considered as gray, absorbing-emitting radiation but non- scattering medium.<br /> &nbsp;</p> https://ultraphysicalsciences.org/paper/902/ Radiation Convection Variable temperature Heat transfer Porous media
