WebChoked flow usually happens when there is a high pressure drop across the valve. Choked flow begins when a pressure ratio is reached (1.8 for methane) and the gas velocity is at Mach 1 (767.2 MPH). There does not need to be a high flow rate for choked flow to occur. The valve is "choking" the flow back because it has reached sonic flow (Mach 1 ... browning buckmark optical sightWebThe two-phase flow model was used to predict liquid and vapor velocities at the minimum areas of nozzles, which may be useful in predicting erosion rates in valves.
