Based on an engineering background, through numerical simulation of the flow field in the hp turbine of the energy efficient engine ( e3 ), the article research the unsteady flow in a transonic turbine stage, the unsteady phenomena in the stage include the shockwave, wake, shedding vortex, endwall vortex, passage vortex and leakage vortex, etc. there are two shockwaves generated on the vane the tailing edge, one on suction side is named moving shockwave, and name another on pressure side steady shockwave
本文首先對于研究的意義和國內外研究的現狀做了簡要的介紹，再從某工程背景出發，通過對e3發動機高壓渦輪內流場的數值模擬，研究了干涉的周期性的問題，以及渦輪級內常見的非定常現象：激波、尾跡、脫落渦、根腳渦、通道渦、漏流渦。導向器尾緣會出現兩道激波，在吸力面的激波可稱為「運動」激波，壓力面的激波可稱為「定常」激波。 -
This new technology changes from the traditional method by which the induced and compressor wheel separately are designed and produced to a new one by which the one - piece compressor is designed. on the basis of this new technology and the optimum blade profile, the performance of both the compressor and the turbocharger is largely improved. through the heating power calculation of the compressor, the analysis of the surge and the block of the compressor, the test - bed performance test of the turbocharger, the matching test of turbocharger and diesel engine, the propulsion test of the turbocharger on plateau condition, it is proved that the newly - designed compressor not only has high efficiency, but also improves the flow distribution in the high efficiency area so that the propulsion line can run through the high efficiency area

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。 -
Hence, analytical expressions are developed to allow for characterization of the vehicle ’ s dynamics early in the design cycle. the method involves a two - dimensional hypersonic aerodynamic analysis utilizing newtonian theory, coupled with a one - dimensional aero / thermo analysis of the flow in the engine of the vehicle
方法中包括一個應用牛頓力學理論的二維的高超聲速空氣動力學分析以及一個一維的氣動/熱分析，後者用於模型發動機中的流體分析。 -
When volume efficiency is computed by an engine cycle simulation considering gas flow in intake and exhaust manifold as one - dimensional unsteady flow, improperly given parameters in the simulation may cause an error over 5 %
摘要採用進排氣管流動為一維非定常模型的發動機循環模擬方法計算充氣效率時，若模型中給定的參數不合適，可能引起充氣效率的計算誤差超過5 % 。 -
The characteristics of flow in mini - channels at low reynolds numbers are one of the essential components for the design of mte ( micro turbine engine )
