Hello,

I want to simulate the effects of aeration (using air bubble) on stratified dam reservoirs by using OpenFoam. The simulation is imposed on a 2 dimensional vertical field and the purpose is to obtain the velocity field.

I would be so grateful if you could kindly help me in selecting an appropriate solver in OpenFoam to tackle this problem.

Best regards,

Hello Arash

To capture two phase effects in a simulation of a real life dam size problem, I would suggest you look at twoPhaseEulerFoam solver. The other option is interFoam, though I suspect the necessary mesh size will be too large to capture aeration effects which you desire. Though I see it is a 2-D problem, so then interFoam could be an option, though capturing many bubbles becomes very computational intensive. Have a look at the twoPhaseEulerFoam tutorials (bubble column) and the interFoam ones such as the weir Over Flow to determine which will best suite your needs.

Regards,
Brian

Hi Brian,

I have to simulate a 3D aeration tank with a residence time around 2.5 hours. What's the best choice for such as large time scale?

Cheers,
Antonio
