Abstract: A corrected (P2) diffusion equation is presented for the radiation transfer problems by means of an asymptotic expansion and numerical comparisions of LD (linear discontinued finite element),P2 diffusion, simple diffusion and limited flux diffusion are also given.

Key words: radiation transfer, P2 diffusion, limited-flux diffusion
