Good day I trust all well.
I'm new to CFD, OpenFOAM and C++ and would please like assistance on a problem. I want to simulate a Ratio Pressure Reducing valve where when the fluid pressure interacts (hits) with the piston inside the valve it pushes/slides backwards and fluid can flow through. Then when fluid flow/pressure drops valve closes again because force on valve drops. I have attached a picture of the part where the blue piston is all the way to the left and valve is fully open. Fluid flows in from right to left. I looked at rigidBodyDynamics to use for dynamicMeshDict. I exported the piston as a .stl file and used rigidBody to read .stl file in dynamicMeshDict. This did not work. I have no idea how te mesh the valve housing then mesh the piston and make the piston translate forward and backword. I tried changing and adapting DTCHullMoving and floatingObject but no luck. if anybody can help me or fill me in on a simpler way that would be much appreciated. Thanks in advance. |
