Hello, i have simulation with Re=10.000/20.00 in a pipe with 2 bends in a cyclic setup. I want to compare my kOmega with an Les simulation as a second check. kOmemga gave something abit higher than for a straight pipe (which seemed reseaonable), but les was waay lower almost laminar). Therefore i made a new study for straight pipe. kOmega gives more or less the corret value at Nu=27, while LES give me 2.5. Ive tried reducing Co, and ive tried refining the mesh, but it doesnt really have any impact. I have also tried initialising U-with a skewed velocity to make sure turbulence would be created - it didnt help either. Then i tried increasing Re = 20.000 and saw the same pattern.. Any tips are appreciated!
