摘要
利用任意拉格朗日—欧拉 (ALE)方法 ,通过直接对N—S方程进行数值求解 ,对渐缩有障碍弯道内的气体流动进行数值模拟研究。通过对不同尺度障碍物的局部阻力因数进行数值模拟 ,所得计算结果与传统的经验基本吻合 。
In this paper, ALE technique is used to simulate air flow in a gradually contract curve with an obstruction in it. The simulation pictures the process of air flow through the curve and the curve local resistance factors. The results of simulation are reasonable and acceptable. The simulation puts forward a new method for the curve design.
