Abstract

Temperature profiles in a fluid flow inside a porous vertical channel influenced by the presence of variable
thermal conductivity and dissipation function are important features in the study of magneto hydro dynamics.
In this study, the effects of temperature and variable fluid properties on unsteady hydro magnetic flow of a
radiating gas inside a porous were investigated. The coupled nonlinear partial differential equations derived
from the governing equations of the fluid were solved by the method of successive approximation techniques. It
was found that the dissipation function was completely neglected at the centre line but maximum at the wall of
the channel where a fully developed temperature profiles reached its peak. The heat flow balances at the wall
due to high temperature and dissipation function
