Thermal Radiation Effect on Fully Developed Mixed Convection Flow in a Vertical Channel

Abstract

The effect of radiation on the steady mixed convection flow in a vertical channel is investigated for laminar and fully developed flow regime. The Rosseland approximation is considered in the modelling of the conduction-radiation heat transfer and temperatures of the walls are assumed constants.  The governing equations are expressed in non-dimensional form and are solved both analytically and numerically. It was found that there is a decrease in reversal flow with an increase in the radiation parameters.
