how to give boundary condition....urgent plz reply frnds
 

i have two cases first one with clean inlet flow compressor and second one is distorted flow compressor (using distorted screen).

First case inlet axial velocity is uniform/constant.

Second case i have generated inlet axial velocity profile which changes circumferentially.

i know values at design point rpm, mass flow, axial velocity(distorted n undistorted both)
what is the basic/logic behind using boundary condition at inlet & outlet?
Total P Total T static P static T Mass flow velocity are the option available in CFX while choosing BC.

thanks & regards
Prashant
