Abstract

On the basis of the results of measurements and numerical modeling, the interaction of turbulent jets (swirling and without swirling) with the surrounding environment is analyzed. It is shown that the mechanism of the effect of the jet on the surrounding environment is associated with a decrease in the static pressure in the jet. The nature of the influx of the external medium into the jet is independent of the mechanism of the appearance of reduced pressure, and the kinetic energy of the jet is an energy source for the induced flow.

湍流射流对周围环境的动态影响

摘要

根据测量结果和数值模型，分析了湍流射流（旋流和无涡流）与周围环境的相互作用。结果表明，射流对周围环境的影响机理与射流中静压力的降低有关。外部介质流入射流的性质与出现减压的机理无关，射流的动能是诱导流的能量来源。
