Compressibility becomes important for High Speed Flows where M > 0.3 • M < 0.3 – Subsonic & incompressible • 0.3 < 0.8 – Subsonic & compressible • 0.8 < 1.2 – transonic flow – shock waves appear WebJul 16, 2016 · Under these conditions we can show that the change in velocity is related to the change in area by the following equation: ... and therefore the stagnation temperature also does not change across the shock wave. ... but because the flow does not reach the critical pressure ratio , the flow does not reach Mach 1 at the throat. Hence, the flow ...
