Cyclone Separator
 

Hallo, i want to know if it is necessary to precise an operating pressure or a guage pressue to simulate the motion in a cyclone separator with a mach number less then 0.7 (supposition of incompressibility) My other question is that the simulation converge with a low number of cells (10000-35000) by the RSM model, when the mesh is rafined the solution diverge, ho can tell me what's the problem? thanks

Ma=0.7 is compressible flow,

sorry it's a mistake i want to say the invers (higher than 0.7)
