star Guest Posts: n/a	Hello guys, I am trying to simulate the mixing of helium in air.Helium is being injected from bottom at some velocity in a cylinder initially filled with air at atmospheric pressure.an outlet is provided at the top of cylinder. I am trying to match the results with some experimental data. USING- 1)KE standard model for turbulence 2)transport method of solution I am not getting good reults (conc. of helium)for half portion along the height from bottom. Does anybody is doing such type of problem. kindly forward your suggestions.
