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 … WitrynaIn a high-speed subsonic jet impinging on a flat plate, the surface pressure fluctuations have a broad spectrum due to the turbulent nature of the high-Reynolds-number jet. However, these pressure fluctuations dramatically change their pattern into almost periodic waves, if the plate is placed close to the nozzle (x0/d< 7·5).
WitrynaThese jets are generated by a reciprocating piston that oscillates in a cavity behind a circular orifice. Instantaneous two-dimensional in-plane velocity fields are measured in a plane containing the orifice axis using multigrid/multipass cross-correlation digital particle image velocimetry. Witryna2 lut 2011 · Several configurations have been tested such as: jets issuing from orifices or round and slot nozzles different types of jet arrays; flat and curved impingement surfaces, normal and inclined impingement, etc. Only the simple geometry of a single jet impinging on a flat surface is treated below.
