The development and disappearance of the acoustic oscillations are influenced by the nozzle throat size and open - time of the plug
計算結果表明,這些影響包括了聲振的強度、阻尼和頻率,發動機點火后噴管喉部尺寸和堵蓋打開的時間影響到振蕩波的發展和消失。The analytical mode is based on the theory of sound propagation in layered media. the concept of equivalent parameters is established. the absorption of sound energy by damping layer ' s is represented by use of complex sound impedance
解析模型以分層介質中的波動理論為基礎,建立了等效參數的概念,並運用聲阻抗的復數表示法把阻尼層對介質層聲能吸收的影響都考慮進去,通過比較敷設消聲覆蓋層前後多層傳遞損失的差異來獲得消聲層的效率。
