Mathematical Modelling of Transonic Flows in 2D Cascade
flows in a 2D cascade near the so-called choked regime using 3 basic models: potential, inviscid and viscous flows. We consider also several possible formulations cascade and DCA 8% cascade. The numerical results for trans...

Effect of wall roughness on secondary flow choking in supersonic air ejector with adjustable motive nozzle
almost no influence on secondary flow choking when choking occured geometrically before the mixing chamber. By contrast, when choking occurred within the mixing sheds light on secondary flow choking

Critical pressure in liquids due to dynamic choking
The existence of a critical pressure ratio due to gas-dynamic choking is well of the compressible flow of liquids. It has been shown that even though an ideal gas reduction of this pressure does not lead to an increase in mass f...
