Blow off valve flow simulation

Bruno Batarelo Mar 23, 2016 6:31 AM

Hi, is it possible to simulate a flow of liquid passing through blow off valve in solid works and get a forces being exerted on the valve face? Problem is that valve consists of orifice and a thin shim covering it completely (restraint). Blow off functionality is given by the properties of shim(s) which bend in different patterns given the number of orifices they cover.

Thank you,

Bruno

You would need to model the shims as bent, because there is no multiphysics simultaneous solving of CFD and FEA analysis in Flow Sim. You can only solve for rigid fixed geometry. If you model the geometry correctly, then you can obtain pressure induced forces on your geometry.

  This is the answer I was afraid of
  Given that it's completely not my industry and I don't know how to model such deflections, do you know if Solidworks can be utilized for determining a shape of a body if forces are applied in some way to it? If I could achieve that and possibly use the deflected form, then that would give me approximate shape of the object I could then set as a restraint.
  
  Thanks again,
  Bruno

    You could use an FEA program (for example, SolidWorks Simulation.)
