两相流水击模型对输送防护措施效果的计算分析

Computational analysis of water hammer prevention devices for solid\|liquid two\|phase flow pipelines

本文针对固液两相流的特点,建立了水击计算的运动方程及连续方程,并采用新方程对矿山常采用的容积泵输送中使用的储气罐、泄压阀、缓闭逆止阀等减缓水击压力的防护措施进行了计算分析,得出储气罐。

According to the characteristics of solid\|liquid two\|phase flow,the equation of motion and the equation of continuity for hammer computation are deduced in this paper.The equations are applied to analyze the effect of different prevention deveces used to relieve water hammer pressure in pipeline transport with displacement pumps.It is concluded that the air vessel and pressure relief valve are better than other devices.
