WebConverging-diverging nozzles, also known as de Laval nozzles, are designed to obtain a supersonic flow. The “correct” or design operation is for subsonic flow between points 1 and 2, reaching sonic flow at location 2 (the throat), and then isentropic supersonic flow in the diverging section from points 2 to 3. WebThe gas flow through a de Laval nozzle is isentropic(gas entropyis nearly constant). In a subsonic flow, soundwill propagate through the gas. At the "throat", where the cross-sectional area is at its minimum, the gas velocity …
