Description

Thermal radiation transport simulations are sensitive to the value of T used in the thermal emission source term. Monte Carlo thermal radiation transport simulations typically employ the Fleck and Cummings semi-implicit approximation or emission temperature, which uses the tn value of temperature. This can lead to thermodynamically incorrect behavior, such as matter temperatures which exceed the temperature of adjacent radiation sources. This work describes work on a Monte Carlo thermal radiation transport algorithm which is fully implicit in the emission temperature. This algorithm calculates the value of Tn+1 for use in the thermal emission term in an iterative way. (authors)
