FW-H sources in control valves
 

hi ...
i have a 5 stage multi hole trim ( anti-noise trim ) which i am gonna run it on Fluent. the reciever is 1 meter away from the center of the trim and in the pipe. something like (1,0,0). i want to calculate OSPL in this point but i dont know which parts of the geometry should be defined as sources. i myself think that all of the walls should be defined as sources but i have doubts.
