afterburner combustion 中文意思是什麼

afterburner combustion 解釋
加力燃燒室燃燒
  • afterburner : 【航空】補燃器，加力燃燒室。
  • combustion : n. 1. 燃燒，發火，點火。2. （有機體內營養料的）氧化。3. 騷動。
  1. Afterburner systems, designed to operate up to a stoichiometric overall mixture strength, are always fairly close to combustion instability or screech.

    要使加力燃燒系統在理論化學組成量的總混合濃度下還在一直工作，這樣的設計通常都很接近於不穩定燃燒或振蕩燃燒。
  2. Afterburner combustion system

    后燃燒系統
  3. In arbitrary curvilinear coordinates, the wall function is used for treating near wall regions. the influences of two different inlet gas parameter distributions and turbulent combustion models, as well as three different afterburners on turbulent combustion flow fields and wall temperature profiles are calculated. comparisons of experiment results and calculations results show that second - moment combustion model is reasonable for modeling turbulent reacting flows, inlet gas parameter distributions is more important. calculation method is reliable and can be used for the optimum design of afterburner

    數值研究三種不同幾何形狀、兩種進口氣流參數分佈、兩種紊流燃燒模型等對加力室內各氣流參數、隔熱屏和加力室筒體壁面溫度分佈的影響，計算結果與試驗數據比較表明:不同幾何形狀加力室對加力室內紊流燃燒流場的影響要比進口氣流參數分佈大些，正確給定進口氣流參數分佈較為重要，二階矩紊流燃燒模型更適用摸擬三維紊流燃燒流動，計算方法合理，編制的計算程序可靠，可供加力燃燒室優化設計用。
  4. In arbitrary curvilinear coordinate systems, three dimensional turbulent combustion flow fields of the three kinds of turbofan engine afterburner with the longitudinal heat shield 、 outer cold flow and the jet nozzle are simulated. the three - dimensional body - fitted grids are generated by an elliptical grid generation procedure and zone method

    本文在任意曲線坐標系統下對三種帶有縱向隔熱屏、外冷卻通道和尾噴管的渦扇發動機加力燃燒室的三維紊流燃燒流場進行數值模擬。
