I tried to use Simple algorithm as a solver but it didn't work. Then i changed turbulence model to k-e realizable with Enhanced Wall Treatment. With this change residuals converged and selected variables became stabil. What is the reason of that?

Also, in the end of two simulations, results show that:

I think there is a big difference. I don't know it is true to compare that way but fluctuations occur around particular value.
