Web11 apr. 2024 · In accordance with high-speed schlieren results, the flow instabilities in the subsonic–supersonic mixing layer with a convective Mach number of 0.19 are investigated in detail. In the incipient stage of the mixing layer, wave structures caused by the pressure gradient affect the evolution of the Kelvin–Helmholtz vortexes. Web24 jun. 2024 · Subsonic speeds are anything much slower than Mach 1. Here, shocks do not form because disturbances can still propagate faster than the gas flows, making aerodynamic control relatively easy. Launch vehicles accelerate so rapidly that they don’t spend much time here. Transonic speeds are around Mach 1.
