screen
 

Dear CFX users, recently I am modelling a subsonic inlet for turboprop engine. I am using CFX 5.5. I would like to model on input for engine (in fact output from computed domain) a screen with certain pressure drop coefficient. I have tested to model screen using fluid subdomain on a simple testcase of pipe with quadratik loss coef. and also by definition of negative momentum source as pres. loss, but results are quite strange. Could anyone help me how to define right values of these pressure loss inputs for subdomain, or simply how to model screen?

Thank you very much for your time.
