-
摘要: 分析了彎曲通道內氣流流動狀態,確定了氣相流場的控制方程和邊界條件,建立了通道內計算流動阻力的有限差分的數學模型和計算機程序,通過理論計算和實驗分析了流道的幾何參數對阻力的影響。計算結果與實驗數據相符合。Abstract: The flow state of airflow in the bend passages is analyzed. The control equation and boundary condition of the gas phase flows are determined. The mathematical model of the finite difference and the computer program are presented. The effect of geometric parameter of the passages on the resistance are analyzed by theoretical computations and experiment, and calculated results and experimental data is good agreement.
