Abstract
The present study is devoted to study the influence of radiation and buoyancy on heat and mass transfer characteristics of the selfsimilar boundary layer flows induced by continuous surfaces having a prescribed variable surface temperature and stretched with rapidly decreasing power law velocities. The effects of mixed convection flow with suction in the presence of a quiescent fluid medium of constant temperature are considered. Rosseland approximation is used to describe the radiative heat flux in the energy equation. The transformed governing equations are solved numerically and the velocity and temperature profiles as well as the local Nusselt number and skin friction coefficient are presented. Results show that the effect of radiation is to keep the molten mass away from the slot warmer, reduces the friction factor and increases the heat transfer rate compared to the case in the absence of radiation.
