摘要
针对空气阀水锤仿真中出现的"虚假"振荡,本文研究了其产生的原因,分析了复合型空气阀结构特点,重点探讨了怀特法在实际应用中存在的不足;着重介绍了"两阶段"空气阀边界条件,并结合工程实例,论证了该方法可以得到较好的仿真效果。
Pointing to the false oscillation in simulating specifically for air valve water hammer, this paper analyzes the reason and combines the structures characteristics of composite type air valves. At last, it adopts two-stage method to imitate the whole fluid transient and gets a better simulation result.
