| 摘 要： | 阐述了管道中水击压力波传播的原理,在考虑管壁和流体粘性摩擦的条件下,建立水击2-方程模型进行数值模拟,并与经典水击模型进行了对比仿真分析.结果表明:水击过程中,两模型的阀门处最大压力增值和周期均相同,分别为127 m水柱和72 s;2-方程模型的管路压力值逐渐衰减,直至消失.

| Abstract: | The principle of spread of water-hammer pressure-wave in pipeline is described,and in the condition of viscous friction of wall and fluid,2-equation model of water-hammer is established and simulated numerically and compared with the classical water-hammer model.The results show that in the process of water hamme,the value of the maximum pressure and period of two models in the valve are the same,which is 127m water column and 72s respectively.And the pressure of 2-equation model is gradually fading until disappearance. |
