Soll is on a distinguished road
I am now working on simulating compressor dynamic with variable rotational speed. I plan to do it in a MRF system and set the rotational speed vary with time or time step. However I cannot find where to input this variable.
I read the documents and it shows the momentum equation in MRF has included the angular acceleration term, which implies its ability to deal with this problem?
Does anyone know if this is possible in Fluent? Using UDF or TUI or any other ways.
