Material properties:absoption and scattering coeff -- CFD Online Discussion Forums

December 4, 2008, 02:21	Material properties:absoption and scattering coeff	#1
Novice Guest Posts: n/a	Hi all, I am simulating the radiation of a UV lamp inside a cylindrical volume(cylinder contains water) using Dicrete ordinates-non gray model. When I activate the DO model FLUENT is giving a message that the material properties have to be changed(and new propety fields like absorption coeff; scattering coeff appears in the materials panel). How to calculate the absoption and Scattering coefficients??? Please let me know the procedure how to calculate these coefficients. Thanks in advance
