The shearing layer is carried by the jet and the eddy is formed because of the instability and selective amplification of shearing layer which will propagate to the downstream. as the eddy impacts the impinging wall, a wave of pressure disturbance with certain frequency is induced. this wave then propagates to the upstream with high speed, and results in the overlap and amplification of the waves when the frequencies of them are close with each other
當前噴嘴流束中的不穩定擾動波在穿過腔內的剪切層時,剪切層對其有選擇放大作用,形成渦環結構,剪切流動中渦環與碰撞壁撞擊,在碰撞區域產生壓力擾動波並向上游反射,在上游剪切層分離處誘發新的擾動的產生,當新擾動與原擾動匹配時,射流上游就被不斷地受到周期性激勵,腔內就產生流體自激振蕩並在後噴嘴出口形成脈沖射流。Besides this paper discusses the sorting principle of micro diameter glass bead and brings forward sorting roundness with motion resistance and knocked - on reflection principle
此外,還討論了作為準流體的微徑玻璃珠分選原理,提出可通過運動阻力和平面撞擊反射原理相結合篩分得到圓形微徑玻璃珠。
