Want to get secondary flow in 3D turbine rotor cascade
 

Hi I m new to the fluent and I have to solve 3D Turbine rotor cascade model to get the secondary flow at the outlet. I have several questions regrading this

1) For compressible flow model which turbulence model should I use ?
2/ How much I take inlet gauge pressure ?
3) I m solving for minimizing pressure loss ,so how can I get secondary flow at the outlet ?
4) how can I see secondary flow in fluent ? I want to see at the outlet of the 3D Turbine blade .

Please help me as soon as possible .Its very urgent
