Denisty Current Turbulent Simulation Issues
3 Attachment(s)
Hi All,
I am trying to simulate a density current within a long water tank. A small section of higher density fluid (salt water = 1060kg/m^3) is on the left and the rest is standard water (1000kg/m^3). I am using buoyantBoussinesqPimpleFoam for the simulation and it starts as if a lock gate is instantaneously removed. I believe I have the correct properties for water and correct boundary conditions. I have attached a picture of the initial setup. However, I have attached a picture of my laminar simulation after the first couple of time steps which is what I would expect. But for my turbulent flow, the temperature seems to immediately diffusive and I'm not too sure this is correct as in the picture I have attached. I am comparing to this video: https://www.youtube.com/watch?v=4ENuf24gEUw in which you can clearing see the eddies being formed etc. Does anyone have any ideas why my simulation seems incorrect? I can send any of the simulation information you may need. (Also, where is the best place to obtain property values of your medium in question? I assume experimental but I don't know of/can't find a good online source) Thanks, Bish |
