Hello CFD Online Community,
I'm currently simulating a vertical submerged water jet impinging on a mobile sand bed. I'm using the VOF multiphase model but I'm not sure if I should choose k-epsilon or k-omega for my turbulence model. I have read that k-epsilon is not very well specified at the 'wall'. I also have a question about that: by 'wall' do they mean a boundary defined as 'wall' or can it be a boundary between the two phases (sand and water)? Thanks in advance for your time and support. |
