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

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?
