Simulation of mixing of two compressible fluids
 

Hi,

I am trying to simulate a cylinder which is filled with air and He gas is entering from the bottom and an outlet is provided at the top. The dispersion of He gas in the cylinder is dominated by diffusion. Turbulence is induced in the system by buoyancy.

I am unable to get which kind of OpenFOAM solver will mimic this situation.

Can anybody help me on this front ?

with regards,
-Gopal.
