Partial Moment Entropy Approximation to Radiative Heat Transfer

Abstract

A new approximation to Radiative Heat Transfer, intermediate betweeen moment models and discrete ordinates, is introduced. We consider a moment system with general partitions of velocity space, closed by an entropy minimization principle. We give physical and mathematical reasons for this choice of model and study its properties. A numerical example is presented. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
