    Unphysical heating under high pressure

    Max Fomitchev-Zamilov

      Hello -


      I am trying to model a high-pressure nozzle in SolidWorks Flow Simulation and I get unphysical results.

      Specifically, I have a very simple system, which is a combination of stock pipe (inlet/source) and stock nozzle (outlet/sink).

      The inlet mass flow rate is ~1 lb/s, which gives me the inlet pipe pressure of ~10,000 psi.

      The inlet temperature is set at 80F.

      Liquid - water.

      However, when I model this configuration the water in the inlet pipe heats up to unphysical temperatures, which go up with the flow rate.

      I get hundreds of degrees F in my inlet pipe, which cannot be correct. So, what's wrong? Is SolidWorks incapable of accurately modeling fluid flow with pressures in the thousands of PSI range?

      Thank you in advance,
