free-jet nozzle 中文意思是什麼
free-jet nozzle
解釋
自由射流噴管-
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。
