| Abstract: | 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. |
