I'm getting different lift coefficients with different models.
I've checked many times, my conditions are the same in both models. Can anyone please tell, what could be the reason for this? K Epsilon - 0.12 K Omega SST - 0.06 Last edited by Pacificdubey; November 21, 2019 at 05:24. |

Your question is quite arbitrary and I suggest to provide more details for your case if you like more detailed answers.
Anyways, it is expected that different turbulence models give different results. |

Another important factor is what wall model you are using for the k-epsilon model. My experience is that this can give quite different results, because different wall models are suitable for different mesh densities and flow conditions.
Also, I assume you are using inflation layers on the walls? |
