Christoph_84 Member Join Date: Nov 2009 Posts: 34 Rep Power: 16	Hello, I work on a axial symmetric methane flame. For the radiation I first used the DO model, how worked fine. After this I want to check the results of the DTRM, I tried different numbers of Rays (Phi and Theta) and get three types of results: Same result like no radiation is used Very low temperature and lots of fluctuations Flame extinguish (it’s possible for the combustion Model) For the absorption coefficient I use the WSGGM cell based. Is it possible to use the DTRM model for this case? If it is possible what kind mistakes I made?
