Finite Element Simulation of Radiative Heat Transfer in Absorbing and Scattering Media

摘要

A finite element formulation based on the original discrete-ordinate equation is developed for the simulation of radiative heat transfer in absorbing and scattering media. Two cases of radiative heat transfer in two-dimensional rectangular enclosure filled with semitransparent media are examined to verify this new formulation. The results show that the finite element formulation presented in this Note has a good accuracy in solving the radiative heat transfer in absorbing and scattering media. In comparison with the conventional finite element method for radiative heat transfer, the new finite element formulation avoids the complex geometrical integration and can be used to solve the radiative heat transfer in anisotropically scattering media.
