Valves are frequently used in compressors and pumps to control the flow processes. Ansys Forte can be used to simulate the flows around the valves as they open and close. In such applications, the valves' displacement and motion are caused by local flow pressure, and their prediction is coupled with the prediction of flow field. Therefore, simulating flows involving such valves requires simulation of Fluid-Structure Interaction (FSI) using either Forte's built-in FSI capabilities or a coupled simulation of Forte and another Ansys software using System Coupling. Refer to the following tutorials for such applications:
Two-Stage Rotary Compressor in the Ansys Forte Tutorials contains a Reed valve to control the discharge process. The movement of the Reed valve is computed with Forte's built-in FSI feature and a beam-bending model.
Piston Compression Pump With Built-in FSI in the Ansys Forte Tutorials contains one intake and one discharge valve, whose motion are computed with Forte's FSI feature and a spring-mass model.
Valved Pulse-Jet With Built-in FSI in the Ansys Forte Tutorials is another example of using the Reed valves, whose motions are computed with Forte's built-in FSI feature and the beam-bending model.
Note: In certain applications, the valves are very thin plates. The mesh controls for these valves need special attention as the local mesh resolution must meet certain requirements. Refer to Set Mesh Refinement Controls Near a Very Thin Plate.
