Question about turbulence modeling choose for this case
 
Hi


I'm using K-Omega model to detect the pressure drop of my flow. But from the comparison with the experimental data, my simulation result around a strong fluid streamline curvature is very inaccurate.(There's a corner in my geometry. So that the flow suddenly turns 90 degrees.) The simulation pressure drop result at the corner is much larger than the experimental data. It seems that the K-Omega model doesn't work well for the strong fluid curvature. May I ask what turbulence model shall I choose for this case?

Thank you very much!
