Question about standard k-e and low-re-ke
I'm using a UDF v2-f model. The v2-f model uses a different formulation for epsilon, but the same formulation for k as the k-e model.
As far as I can tell, the only difference between the k-e and low-re-ke models are the damping functions included in the epsilon transport equation. So my first question is, is that true? If it's true, then why am I seeing different results for my v2-f model when I use the standard k-e model's k equation and the low-re-ke model's k equation? |
Im no pro, but i figued you could use some input.
Damping ratio shouldnt change the end result, but it can... It is possible that one of your solutions has found a "local min" for the residuals and has converged on a phantom solution as opposed to the desired solution. I would try increasing the mesh resolution and attempt the model comparison again. Best of Luck |
