curvilinear coordinates 中文意思是什麼
-
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。 -
