Effect of Anisotropic Scattering on Heat Transfer Combined Conduction and Radiation in a Gray Dispersed Medium

Abstract

Effects of an anisotropic. scattering on heat tranfer combined conduction and radia・ tion in an absorbing, emitting and anisotropically-scattering medium are investigated theoretically. Consideration is given to a one-dimensional system bounded by two parallel gray, dif〔use and isothermal walls. First, to select a useful phase function for evaluation of heat transfer characterist1cs, three kinds of one-parameter phase function (alinear phase function, the Kagiwada・Kalaba phρse function and the Henyey-Greenstein phase function)are examined. Consequently, we丘nd that the Henyey-Greenstein phase function is most useful. Then, the effects of anisotropic scattering on temperature profiles, heat transfer characteristics and heat nux distributions are investjgated systematically by means of this phase function. Furthermore the e丘ects of the anisotropic scattering on heat transfer by thermal radiation alone are examined, too.
