Witryna10 kwi 2024 · The flow and acoustic fields of jets at a Mach number of 3.1 impinging on a plate at 15 D of the jet nozzle exit, where D is the nozzle diameter, have been investigated using highly resolved large-eddy simulations. The plate is perforated with a hole of diameter h = 1.33 D, 2 D, 3 D, or 4 D. Witryna26 kwi 2006 · These characteristics provide a natural explanation of why the unsteady flow fields of subsonic impinging jets must be axisymmetric, whereas those for supersonic jets may be either axisymmetric or helical (flapping). In addition they also offer, for the first time, an explanation as to why no stable impingement tones have …

Witryna1 kwi 2024 · A jet impinging a surface is an important phenomenon in the fields of fluid mechanics and heat transfer. This technique can be used to increase heat transfer between the fluid and the surface. Impinging jets are often used when there is a strong demand for localized heat exchange on a surface.
