Mixing Plane - upstream influence -- CFD Online Discussion Forums

October 6, 2008, 10:24	Mixing Plane - upstream influence	#1
sonja Guest Posts: n/a	Hello! I have simulated a compressor wheel: full 360° of the stator and only one blade of the rotor. If I plot velocity, pressure etc. in CFX POST, I can see an obvious upstream influence of the modelled blade. Something must be wrong with my boundary conditions (I set static pressure at the outlet of the rotor and at the outlet of the stator where the not-simulated blades would be. Both pressure values are given by another simulation. At the inlet I have a velocity vector profile.) What kind of boundary conditions would you suggest? What gives stable results? Thanks!
