Web22 de jan. de 2024 · The flow field around supersonic aircraft is usually accompanied by complex flow phenomena, such as shock wave and shock wave/boundary layer interaction, which cause some adverse effects on aircraft performance. Seeking effective flow control methods has been a hot topic for many researchers. As an important method to improve … WebThis module deals with a plane shock normal to the flow direction. This case represents the simplest example of a shock, in that changes in flow properties occur only in the direction of flow; thus, it can be treated with the equations of one-dimensional gas dynamics. The next module will cover the oblique shock wave, positioned at an angle to cancel forwarding calls

The four modes of nozzle operation are fully subsonic, normal shock in the diverging section, overexpanded, and underexpanded. They are defined by five values of back pressure , which are often expressed as the ratio of back pressure to supply stagnation pressure .

Web8 de out. de 2024 · $\begingroup$ "Optimal/required" is probably the wrong question way to think about it. The point is that once the flow reaches Mach 1, there is no way for a pressure change to propagate upstream. Therefore, the inlet side of the nozzle can't "know" anything about what happens after the flow reaches Mach 1 at the throat of the nozzle, so …
