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. in car flip down tv dvddvd screen saver hitting the corner gifWitryna23 paź 2024 · Jet impingement cooling is one of the most effective heat transfer enhancement technology, which is commonly used in gas turbine vane cooling, especially for the pressure side of turbine vane [ 1 ].
