Experimental Study on Two Phase Nozzle [PDF]
, 2007 本研究首先設計與製作一二相氣液噴射系統架構，使噴嘴的出口速度達氣液混合液的聲速，並設計三個不同噴嘴出口的角度，來比較出口擴張對推力的影響。由量測不同空氣流量下所產生的推力發現：(1)二相氣液噴射系統噴入壓縮空氣可以增加推力、(2)研究中以半錐角22.5度的噴嘴出口效果最佳，最大推力在有噴入壓縮空氣1300L/min時可達沒有壓縮空氣的3倍。 第二部分是將設計與製作一二相流噴嘴於自由流場中進行拖行實驗，試著以壓縮空氣做為推進的動力來源，其效果為何？實驗過程中同樣噴入不同的空氣流量，來量測推力的變化。
