Zahidipe13 New Member Md Zahid Hasan Join Date: Aug 2020 Posts: 1 Rep Power: 0	Dear Experts, I am trying to develop a CFD simulation for Suction, Compression, and Discharge in a Refrigerator Reciprocating Compressor. There are suction valves and Discharge valves which are opened by pressure. When the piston travels TDC to BDC the suction valve opens. After the compression, the discharge valve opens. How can I develop this simulation model using UDF or CFX. My question is. we have to specify motion in suction or discharge valves in UDF but in actual the motion is dependent on pressure. In CFX how can I make such dependent motion?
