Web阻流（Choked flow）也稱為阻塞流，是流體動力學中，在可壓縮流中的效應，其中的流體速度受到限制（受到阻塞），和文丘里效应效應有關。 當特定压强及温度的流體經過管路突縮位置（例如拉伐尔喷管的喉部或是管路的閥門）到壓力較低的環境下，其流體速度會增加。 WebChoked flow of a fluid is a fluid dynamic condition caused by the Venturi effect.When a flowing fluid at a certain pressure and temperature flows through a restriction (such as the hole in an orifice plate or a valve in a pipe) into a lower pressure environment, under the conservation of mass the fluid velocity must increase for initially subsonic upstream …
