Dear all,
Can anyone please explain how diffusion term (turbulent flows) is equated for a fluid flow in various turbulence models. Thanks in advance. |

Molecular diffusion is dictated by the physics, the additional contribution given by a modelled turbulent diffusion depends on the model you use. You shoul better elaborate your question, I am not sure about the key of your post... |
