Hi sir, In my thermal fluid flow problem, solution is converging in standard k-epsilon as well as realizable k epsilon model. But, when i go for RNG k epsilon model, solution is not converging, can anybody know the reason? how to rectify the problem?
You should provide us with more information about your case. I cannot help you
Hi sir Antonio Mezzacapo ,
thank u for reply sir,
pipe flow with supercritical Co2, o grid maintained in the mesh , 6laks total mesh number of mesh, PISO algorithm, all flow , heat and turbulent properties are 2nd order upwind scheme, presto for pressure,
no sir @Antonio Mezzacapo, i didnt try, i want only in 2nd order upwind scheme because article mentioned in 2nd order upwind scheme, presto for pressure. K-epsilon RNG for turbulent model.
