I am a PhD student at Jncasr, EMU. I am not from mechanical background. I ve done masters in physics. I am required to simulate a fresh water plume in a stable linear stratified medium. I tried using turbulent k-epsilon model coupled with heat transfer in fluids model. I have included boussinesc approximation as well. The results are not as expected, (turbulant entrainment effect is missing in visualization) can u help me with the boundary conditions and get the correct flow visualization to quantify it.
