nozzle coupling 中文意思是什麼

nozzle coupling 解釋
噴口接合
  • nozzle : n. 管嘴；噴嘴；〈俚語〉鼻子。 a jet [propelling] nozzle 【火箭】尾噴管。
  • coupling : n. 聯結；交尾；【機械工程】管箍；聯結器；軸接；（火車的）車鉤，【電學】耦合。
  1. The coupling from the pulse jet in the nozzle to the unsteady flow in the tube was discussed. and the relations between the parameters of gas charge and discharge, structure, working, flowing in tube and ideal cooling efficiency were established. the theory foundation of the influence of pulse jet on the flowing in the tube and characteristic would be built

    探討了脈動射流與管內非定常流動的耦合問題，建立了脈動射流有關參數如進、排氣參數、結構參數、運行參數等和振蕩管內流動參數及理想製冷效率之間的普遍聯系，為研究脈動射流參數對振蕩管內流動及其性能的影響打下了理論基礎。
  2. Water - fittings for house installation ; boltings with flat seal ; one side threaded coupling with inside - thread, on the other side steel tube nozzle, copper tube nozzle or sleeve pn 10

  4. Flow details of measurement indicate that the coupling of periodic separated flow ( such as low frequency swinging of separation line ) with nozzle flow may cause aft - end internal flow unsteady. recirculation flow gains more energy from the main flow, at the same time the turbulence intensity increases

    通過對測量結果的分析，我們認為分離流動的周期性（如分離線的低頻擺動）與噴管流動相耦合，會造成燃燒室尾部流動的非穩態效應增強，增加了迴流區從主流中獲得的能量，也加劇了流場的湍流脈動。
