Transient stator-rotor interface
I am trying to get a solution for transient stator-rotor simulation. 23 stators, 29 rotors. I am using 1 stator and 1 rotor in the simulation. The initial conditions are taken from the Frozen rotor results. I am having problems at the interface, I guess. My stator wake is not transported into the rotor domain. I am attaching three jpeg images taken at different timesteps, showing the "Velocity in stationary domain" distribution at the mid-span. At the domain interface I am selecting "Transient" option, which I guess is true. But, somewhere I am doing something wrong.
By the way, I am simulating only 1 pitch, and dividing it into 10 time intervals.
SST k-w, with the Gamma-Theta transitional model is applied to the model.
Has anyone of you encountered such a problem?
Thanks in advance,
I also want to add that my domain interface is not perpendicular to the rotation axis. It is inclined. Do you think that it might affect the interaction of the domains?
I am a newbie in CFD, so please excuse me if I am incorrect. I think you should look at the vectors at the interface rather than contours to get a better idea of what is going wrong over there. Also pressure contours will be able to point out the interface issues more clearly ( which would be evident from huge jump in pressures.
