Advice on simulating gas filternig system

a99 · December 14, 2015, 17:46

Hi everyone,

Basically I am looking so simulate gas filtering through a liquid based on the pressure applied. You can imagine this as a scrubber system (air pollution control devices) hookahs, inhalers, etc...

I am using OpenFoam and pretty new to it but have a solid grasp of it. I was thinking of using similar to interFoam? Not sure how I can simulate pressure applied causing air to go through the liquid (bubbling, filtering?).

Are there previous work on this topic through the use of OpenFoam? Should I use Ansys Fluent in this case? Any help is much appreciated.

Thank you

Hi Kohbodi,
you could try the following BCs at inlet to make air particles enter the fluid.
BCs for inlet: - pressure: 'totalPressure
- velocity: 'pressureInletVelocity'
more then interFoam, I would look for extensions of it such us bubbleFoam or similar.
If you need some help let me know or please write me in private.
Christian
