Ducted propellers
 

Hi,

I meshed an ducted. I used icoFoam and turbFoam as solver for 2 cases, by moved ducted with speed of Vd = 1 m/s in the fluid (water) - Vf = 0 m/s. The second by flow water with speed Vf=1 m/s through the duct - Vd = 0 m/s. On the first case, I have instability problems. On the second case, the result (force) are not convergence.

Does somebody knows which is suitable solver for this case - ducted propeller?

Thank's
