Choked flow video
WebFeb 7, 2024 · Choked flow within a control valve is when the flow will no longer increase with a drop in pressure across a valve or orifice, due to cavitation within the valve body. A choked flow situation typically occurs in a system with constant pressure and flow on both sides of a valve.

Choked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent-divergent nozzle or a valve in a pipe) into a lower pressure environment the fluid velocity increase… WebOct 23, 2012 · 243K views 10 years ago Duxvalves produces a wide range of choke and control valves.
