Porous medium

October 5, 2005, 17:07

Hi-

I have to simulate an aluminum tank that is filled with porous material (e.g- foam). Also, initially, it is filled with liquid (e.g- fuel). There is an outlet at the bottom to drain the liquid from the tank. As the fuel is drained, the vacant pores in the foam are occupied by air. Can anyone suggest me a suitable model to solve this problem. I have tried it on CFD-ACE, and it doesnt work, so want to try it on Fluent.

Regards

Sonia

go for transient VOF model, it works

Thanks Amir...I think this is a good choice...but i believe that VOF is very time consuming for 3-d calculations...
