Effect of Radiative Transfer on the Thermal Instability of a Rotating Fluid Sphere

Abstract

This paper deals with the effect of thermal radiative transfer on the stability of a rotating fluid sphere of constant density and heated within. The problem has been examined for two asymptotic approximations of the radiative transfer equation. For the transparent case the variational principle for solving the relevant equations has been established by assuming the temperature gradient Beta to be constant. It is observed that radiative transfer has a stabilising effect on the fluid motion.
