  1. Sum up, the study of intake port is significant for the design of intake port and the development of engine. at present, the study of flow characters in intake port of engine mainly depends on experiment. numerical simulation is not universal, especially for the engine with dual - intake port

    目前,國內對發動機進氣道的流動特性研究手段主要依靠實驗,在實驗臺上進行大量的實驗,既費時又費力,實驗方法顯得過于陳舊過時,已不能適應現代高性能發動機研製工作的需要,因此,採用多維數值模擬技術是一種有效的研究手段。
  2. There are great differences between ground test of a flight vehicle ' s aerodynamics and that of a dual - mode scramjet when ground test facilities are used to do experiments on a dual - mode scramjet engine, the components of incoming flow and its parameters, including total pressure, total temperature ( or total enthalpy ) and velocity must be simulated. at the same time, since the fuel ' s resident time within a combustor is very short, on the order of one millisecond, it is difficult to measure the flow - fields

    進行雙模態沖壓發動機地面試驗研究時,必須要求試驗設備能模擬實際飛行條件下來流氣體的組分、總壓、總溫(或總焓)以及來流氣體的流動速度;同時由於燃料在燃燒室內駐留的時間很短,一般為毫秒量級,從而使流場物理量的測定顯得非常困難。
