roukaia is on a distinguished road
hello every body
iam simulating 2D combustion chamber of a diesel engine i managed to get the combustion using a patch in temperature
i have used volumetric reaction finite rate / eddy dissipation model
the temperature rises until 1800k but pressure didni't it still const as the cold flow arround 48 bars (with combustion 80 bars)

should i patch pressure too ???????

do you have any idea how can i solve it
any help will be appreciated
