Transient conductive and radiative heat transfer in a rectangular region
Transient conductive and radiative heat transfer in a rectangular region has been studied. The medium is emitting, absorbing, and anisotropically scattering with a refractive index ranging from 1 to 2. It is initially at a uniform temperature and then suddenly exposed to a much colder environment. The solution for temperature distribution involves simultaneously solving the transient energy equation using an implicit finite volume scheme and solving the radiative heat transfer equation using the discrete ordinate method. An 11 x 11 grid and the S{sub 8} method are found to be sufficient for the range of parameters used in this study. Effects of scattering, refractive index and phase function upon the temperature distribution and cooling rates of the medium are investigated.
