Dear all,
I'm simulating a gasoline combustion in a chamber with stagnant gas. I used the non-premixed combustion and a dpm model for the fuel drops injection . I obtained a good evolution of spray combustion with a temperature that increases above 2000K and this is what i expected, but i have a problem with the pressure because it remains the same (101325 Pa) and doesn't increase!
Can you help me?
thank you for your attention

Hello Dr Floyd,
I need your help regarding your Case as mine case is almost similar to yours.
I want to know how you model the stagnant gas inside the chamber while modelling DPM of Fluent where continuous phase need to be having some velocity.
Thanks for your help

hey DRFd, i have the same simulation as you, my probleme is that how you get your mass flow of the injection, i never get the right massflow while the dpm converged.

thanks for your help
