LDV measurements of plane air jet
Abstract
In a two-dimensional (or plane) free air jet flow, the velocity distribution and turbulence characteristics measured by a Laser Doppler velocimeter (LDV) show reasonable agreement with those obtained by hot-wire anemometry (HW). Then, a plane air jet impinging normally on a flat wall, expecially the distribution of center velocity in the impingement region, is also measured in detail by using LDV as well as HW. In addition, the areas of the impingement region are determined by referring to LDV and wall pressure measurements, and thereby both regions of free jet and wall jet are distinguished from the impinging jet.
