摘要
研究在有压出水管路上设置通气孔来消除反水击的方法。通过对水体和气体非恒定流过程的观察和分析,提出了数值计算模型,并用实验进行了验证。在模型实验与数值计算的基础上,对通气后的非恒定流现象进行了分类,为合理地采用通气方法提供了依据。
In this paper, main efforts are made to prevent the reverse waterhammer with the open air vent. A series of experiments are made and a numerical model for predicting the unsteady flow is developed. Results obtained in the two ways agree well. According to these results, a detailed analysis is performed, and then, the optimun air vent size is recomended.
