Hello everybody!
I want to simulate a rotating radial diffuser! I use periodic surface to simulate only 1/13 of all! B.C. are: rotating fluid domain, liquid water inlet mass flow and velocity direction defined in Cylindrical Components opening on outlet domain with Static Pressure for Entrainment (zero gradient) hub and shroud are walls no slip (k-epsilon turbulence model) Periodic surface with rotational periodic. After 110 iterations I have an overflow! How can I resolve the problem? I decreased timescale but without succes! Thank you |
