Heat source function of mass flow
 
Hi,

I am using an energy source to model a combustion. Unfortunately, in Fluent if I used a constant value as heat source, the area (in the region of heat source) with strong flow are colder than the one with steady flow. In reality, the more gas is flowing, the merrier it burns. So I try to write an udf saying that source is proportional to velocity magnitude, but the results where not that good. Has any one a better idea? Thank you
