Dear Mahdi1,
Hi, unfortunately I am not good at this part. RNG is used in your model, but I know that if LES is used, the velocity behind the cylinder will not be steady for ever so in that case you...

Dear Jay,
Hi, I have tried using second order monotonicity preserving for momentum advection, but it still doesn't work. The Re is 135000, 45cm/s, 50cm in depth. And I have tried the Tlen(mixing...

Dear Daniel, thank you for your reply. In my model, the computation region is 5m long divided into 250 grids, 2m wide divided into 100 grids, 0.5m deep divided into 25 grids.
I will try your advice...

flow structure around cylinder
Dear all,
As you can see in the picture, velocity=45cm/s, diameter=30cm, Re=13500, RNG model is used, the grid is fine enough, the flow is steady, usually in this condition the turbulence behind the...
