有压输水管涵检修时的气液二相流瞬变研究

Study on gas-liquid two phase transient flow in the maintenance operation of pressure water transportation pipe culvert

结合wylie的自由气体离散模型,构建了分段低压输水系统因检修操作导致检修箱涵进气的瞬变流数学模型,并结合实例对计算结果进行了分析。该研究可以为长距离有压输水系统的设计和运行管理提供理论依据和技术支持,同时也为二相流的气泡模拟提供一种可供借鉴的思路和方法。

This paper combined with the free gas discrete model of wylie, constructed a transient flow mathematical model of an air inflow to the box culvert result in the maintenance operation of segmented low pressure water system, combining the instance and analysis of the calculation results. The research can provide the theory basis and technical support for the design and operation management of long distance water diversion system, also provide an ideas and methods that can be used for a bubble simulation of two phase flow.
