Hi,
Has anyone used RANS for simulating any moving boundaries (no slip walls)? What are disadvantages of RANS for such problems? I am dealing with separations at the wall as well. Thanks, A E |

You should consider URANS ... A similar flow problem where URANS is quite common is the flow motion during the cycle of a piston in a cylinder. Check in literature for that

A known RANS/URANS model that can treat separation effects is the two-layer k-epsilon. But I don't know if it is good for moving wall.
