Low Inlet Turb. Intensity - SST model not converge
I'm simulating flow in a diffusing bend. The inlet turbulent intensity that I measured from exp is only 0.5%. However, I found it very difficult to converge using such a low TI in SST model (residuals flat at 10^-3 for 1000 steps). I have to set TI as high as 3% to get the solution to converge to 10E-6.
Anyone know how to modify the parameters in SST model to improve the convergence?
