  1. The calculation results indicate that the starting performance of forebody / inlet with wedge - shaped lip is better than that with plane lip at low flight mach number. at high flight mach number, the performance of the forebody / inlets designed by the two methods is approximate. at low flight mach number, the starting performance of forebody / inlet designed by the method of constant shock wave intensity is better

    結果表明:唇口帶楔角的進氣道在低飛行下的起動性能優于唇口平直的進氣道;採用等強度和等角度方法設計的進氣道在高飛行下的性能相近,在低飛行下,採用等強度方法設計的進氣道起動性能較優。
  2. In this dissertation, the pulse jet style, the influence on the shock wave, the flow in the tube and the cooling effect was deeply studied theoretically and experimentally. the influence of the pulse jet style on the forming of shock wave and the shock wave intensity was explored. the initial disconnection style in oscillating tube vented and the initial disconnection breakdown was proposed by different pulse jet style

    本文對脈動射流的型式及其對、管內流動及冷效應的影響進行了較系統的理論和實驗研究,主要包括:探討了脈動射流的型式對形成管內形成及強度的影響,給出了不同脈動射流的型式下振蕩管開口端初始間斷的類型,對初始間斷進行了分解,導出了包含進氣、排氣參及工質物性參的管內入射激波馬赫數mj的表達式,給出了管內形成的三種原因及其所對應的脈動射流型式和具體的工作狀態。
  3. The results show : laser beam far field intensity distribution deflect to the wave length increasing direction, the influence to laser beam far field intensity distribution of different inflow mach number is little than the influence of different inflow pressure ; flow field has more aberration to 1. 315um laser beam than to 10. 6um laser beam

    研究表明光束遠場強度分佈都向流場光程增大的方向偏折,噴流出口的變化對光束遠場強度分佈的影響較小,噴流出口壓力的變化對光束遠場強度分佈的影響較強;在相同的流場結構下,流場對長1 . 315 m光束的干擾要明顯強于對長10 . 6 m光束的干擾。
  4. There are shocklets in the mixing layer with convective mach number 1. 2

    高對流混合層中存在較弱的小間斷。
  5. The velocity distributions, the relative mach number distributions and the flow trace distributions are visualized, and the reasons, which cause bad aerodynamic losses and make the flowfield complicated, are analyzed, including wake, secondary flow, separated flow and the interaction between shock and boundary layer

    顯示壓氣機內的速度場、相對分佈及流動跡線分佈等,並分析造成嚴重損失及使流場趨于復雜紊亂的原因,包括尾跡、二次流、分離流及/附面層干擾等現象。
  6. All the improvements included the modifications on the sound velocity, characteristic mach number and the mach number at the grid interface. several 2d flow fields which had shock, shear flow, rarefaction wave, or turbulent boundary layer and the combination of them were computed

    該格式改進了聲速、特徵的處理方式,對網格界面進行了修正,並求解了含有脫體、斜、剪切流、膨脹扇、及湍流附面層等流動特徵的復雜流動。
  7. Finally, the two dimensional flow in the diffuser is calculated, the results show that the change of ma makes an effect to the performance of the diffuser. owing to the accretion of ma, the action of oblique shock waves and the boundary layer pricks up, the flow separates from the wall where the shock waves impinge on the boundary layer more quickly, the cluster of diamond shock waves becomes larger. moreover, by comparing the change of flow field under different structure parameter, it is found that the augment of length of constant area section alter the structure of fluid field little, a smaller area ratio and larger angle of compression section make the diffuser working better

    最後,針對擴壓器中的二維流場進行了值模擬,結果表明對擴壓器性能影響較大,隨著的增大,擴壓器管道內-附面層干擾加劇,流動從附面層分離相應加劇,目增多;通過比較不同結構參下的擴壓器內流場,發現等直段長度的變化幾乎沒有改變流場結構,只是對局部流場稍有影響,並且在其它參不變的情況下,一定范圍內減小面積比a2 / a1和增大收縮角有利於擴壓器性能的提高。
