WitrynaThe impingement of a supersonic jet upon a surface results in a flow structure rich in complexity (Henderson 1966 ). This complexity is manifested as a variety of compressible and turbulent fluid mechanical phenomena. Significant among these phenomena is the self-reinforcing aeroacoustic feedback process. WitrynaMost of the existing work have investigated the pressure distribution, thrust force, and impingement force. Considering that jet impingement is a complicated phenomenon that is affected by various factors, the initial flow conditions, break conditions, and target conditions in each experimental study are carefully reviewed. granada 17th april 2022 https://pauliz4life.net
