Choked flow is a limiting condition where the mass flow cannot increase with a further decrease in the downstream pressure environment. Mass flow rate of a gas at... · Minimum pressure ratio...

The phenomenon of choke in an open channel flow is completely dependent on the conditions of the flow before (upstream) and after (downstream) the transition ...

Abstract: This paper presents a study on the energy losses and threshold conditions for choking in short, lateral contractions in subcritical open channel flows ...

The condition of choked flow or a choking condition implies that minimum specific energy exists within the transition. Energy losses in expansions and ...

The flow cannot take place with the available specific energy (choking condition). The flow will be critical at section 2 (E2= Ec, y2=yc) and the upstream.

As the height of the hump is increased, choked condition is reached. That is critical flow condition (choked condition) is reached at the hump. Ehump = EC ...

In summary, we found a flow limitation in open capillary channels which is similar to choking in compressible duct flows and open channel flows under gravity.
