Hello experts,

I have a question regarding the twoPhaseEulerFoam/reactingTwoPhaseEulerFoam. I have two phases of water/particles and would like to have my particles stay in the domain. In other words, only water phase can leave the domain. How would I be able to do this? Basically, something that works like rebound BC for the Lagrangian phase in DPMFoam/MPPICFoam.

Thank you very much!

So I tried putting wall boundary conditions for the phase that I want to stay in the domain, but still no success. Meaning zero velocity and zero gradient alpha. Any help please?

Hi Hooman

I did a similar thing in this tutorial, maybe that will help.

Hello,
Can any one tell me that what is major difference in twoPhaseEulerFoam and
reactingTwoPhaseEulerFoam?
Other thing i want to confirm for reactingTwoPhaseEulerFoam: is it based on volume fraction or mass fraction? tutorial are same for both solvers.

Regards,
Umer
