roukaia is on a distinguished road
Hi, I am having serious problems with what seems to be a very straight forward problem.

I have 1 inlets and an outlet. Very simple 2-D space model.

I am using the diesel/Air mixture . I have a good model with very good residuals under non-reacting conditions. I have an acceptable adapted mesh.

Problem: I apply species transport :EDDY DISSIPATION MODEL

Solution runs and the temperature increases to 1100K . inindicating combustion

Now, the residuals are good but the solution is not. The pressure inside the chamber does not increase with increasing even propellant mass flux. The only way I can increase the internal chamber pressure is by patching pressure inside the chamber .

I cant work it out and would be extremely grateful of any assistance.
