FLOW CHARACTERISTICS OF IMPINGING JETS

Impinging jet finds applications in wide variety of engineering problems. In the vertical takeoff and landing of V/STOL, rockets and missile firing applications, the jet impingement plays a vital role in the field of aerospace engineering. As the jet impinges vertically on the launching ground, jet flow might influence the rear part of vehicle and body balance. This may act adversely on the vehicle systems, so there is a necessity to study the jet impinging characteristics for designing proper launching stations to divert the jet flow away from the vehicle vicinity. In order to understand the impingement jet characteristics a thorough study investigation on the behavior of its characteristics is very much necessary. The present problem dealing with a subsonic circular jet impingement on normal planes for Mach number 0.4, 0.8. At an axial distances X/D 1, 5, 10, 15.
