Default RNG turbulent model

Hi,

Running my case with k-e\high Re turbulence model I do obtain convergence, but results show bad agreement with experiment (in particular velocity is much higer than in experiment). With RNG turbulence model my calculation diverges after 38-th iteration. Does this model require any special settings? If anybody has faced the similar problem please share your experience.

Regards,

Julie

Difficult to say without knowing what type of modelling you're doing. I've had quite a bit of success with the ke-quadratic turbulence model in highly swirling flows.
