Hi.I ecounter a problem in my simulation. It's about a combustion course in a heating furnace. The Weighted-Sum-of-Gray-Gases method is used to caculate the absorption coefficient,but the temperature is too low to be accepted. What should i do to solve the problem? Is it more accurate to use this method? thanks

the WSGGM is a good method for the gases like CO2 and H2O. for other materials use ur own value of constant absorption coefficent. any how temp low may be because of some other issues.

thanks for your reply.but i don't know how to calculate this coefficent,and how does fluent take into account the emmission feature of the flue gas ? thanks again
