Dear altruists!

I am hard stuck in this issue for more than one month. When I inject water inside the combustion chamber it is supposed to lower the outlet temperature and velocity which I am getting only using the EDM model. But when I am using a non-premixed combustion model both the temperature and the velocity at the outlet increasing proportionally with the increase of water mass. Someone suggested to me previously that water mass might be pushing combustion flame towards the outlet but I also tried with bigger geometry and lower air-mass flow rate. So I don't think that's the problem here. If you have any ideas or suggestions please help me out.

Thank you.
