Tip leakage flows
 

Helo, I'm preparing a work aiming on tip leakage flows. I need an exemple of a work aiming on incompressible flow in turbomachines using Large Eddy Simulation. I need to know what are the steps i have to follow in CFX-Pre especialy in the inlet conditions. I heard that i must inject a perturbation at the inlet in order to see if this perturbation will stabilyse. Is it true? If yes, help me to do it.

Let me tel you that i have choosen one geometry using BladeGe, I have created a mesh usin TurboGrid, and i have done a simulation in CFX-Pre using SST turbulence model in transient case.

Sinserly.
