free jet 中文意思是什麼
free jet
解釋
自由噴流-
S boasted the same bright flashing eyes of jet, and ripe, round, coral lips. she moved with the light, free step of an arlesienne or an andalusian
美塞苔絲可愛得象塞普勒斯或凱奧斯的希臘美女一樣，她的眼睛烏黑明亮，嘴唇鮮紅嬌嫩，她的步伐就象阿爾婦女和安達盧西亞婦女那樣輕盈和婀娜多姿。 -
And the paper analyzes the physical reasons that the supersonic flow of fadw degrades the optical quality. and the structure of free - vortex jet of fadw is studied using the methods of shadowgraph and lsi, respectively
並利用陰影法和剪切干涉法對該窗口的射流流場結構進行了實驗觀察和測量，對其所涉及的氣動光學現象進行了相應的實驗測量和分析。 -
Because the symmetrical mode of two free shear layers in the jet is destroyed at x / h = 6. 0, the vortex street develops in non - symmetrical ( sinuous ) modes downstream of this station
由於兩剪切層的對稱性在下游x h = 6 . 0處即被破壞，之後渦街完全按非對稱模式發展。 -
The lateral jets are caused to incline to the direction of rotating free flow and to weaken the effect upon base flow. furthermore, the spinning effect upon lateral jet is much stronger than that upon base bleed
與無旋轉情況對比表明，旋轉對彈丸側噴流以及底部流動均有影響，高速旋轉導致側噴射流向旋轉來流方向傾斜，並減弱其對彈底流動的引射。 -
The ratio of mach number between lateral jet and free flow induce intensity degree of jet interaction. it has no obvious difference between two interactions with two types of nozzle exit configuration, rectangle and ellipse. the shock in front of jet results in increase of shock resistance and the jet ejection causes increase of base resistance
研究表明，側噴流與來流馬赫數之比是影響繞流場的重要因素，該值越大則側噴干擾越強烈，矩形和橢圓形兩種側噴口形狀對側噴流場干擾波系的影響並不明顯。 -
The flow field of fadw is very complicated, especially in the free vortex jet zone. so the method is according to the ideal flow, including the design of the asymmetric supersonic laval nozzle and the diffuser
所以，本文所建立的fadw的基本設計方法是理想狀態下的設計方法，其中主要包括非對稱超音速噴管的設計和氣動窗口擴壓器的設計方法。 -
