    Pressure ratio (P_out/P_in) in critical flow is dependent on valve opening?

    Hi, I am developing a solver for multiphase flow valve. I have checked the Tulsa model (Sachdeva1986) and Al-Safran model (Al-Safran2009), and I found the pressure ratio (y = P_out/P_in) for critical flow does not contain the valve opening parameter in both equations. Is it physically...

    Pressure drop vs. Valve opening in Critical flow

    Hi, I am struggling in modeling of multiphase flow valve in oil and gas production pipeline. I am using Hydro long model, and trying to find C_T value (Throttling coefficient) to be matched with the measured pressure drop. One interesting thing I found is for critical flow pressure drop...
