Choking flow

WebJan 15, 2024 · When a choke is present, the amount of energy in the flow upstream of the choke is insufficient to maintain the flow rate downstream; therefore, a choke would cause a reduction in flow rate moving through the constriction (obstruction) at the section causing the choke. This reduced flow rate is known as the transient flow rate. WebChoked flow.

WebApr 19, 2007 · At some point, the flow stops increasing as the downstream pressure decreases. "Choked" implies that the flow experienced is less than the flow predicted by the Cv equation. When the flow measured is 2% less than predicted by the Cv equation, it is said to be "choked". Further reducing the downstream pressure with constant upstream … WebI heard choked flow, or choking the diffuser in multiple explations of porpoising, but as far as I can tell with my limited compressible gas dynamics knowledge, it's a completely different phenomenon, and is not applicable to race cars operating at low Mach numbers.
