摘要
以某河道综合整治工程为例,采用计算流体力学软件结合RNG k-ε紊流模型、VOF方法,对多级跌水水力特性进行了三维数值模拟研究,得到多级跌水、消力坎等部位水流流态、流速等,并计算了消能率.数值模拟真实呈现了河道多级跌水水流流态及流速变化规律,研究成果验证了工程设计方案,为工程设计提供了技术支撑.
Abstract
Taking a river comprehensive improvement project as an example,three-dimensional numerical simulation of multistage fall hydraulic characteristics was carried out,using computational fluid dynamics software combined with RNG k-ε turbulence model and VOF method.The flow patterns and velocity of hydraulic drops and stilling basin were obtained,and the energy dissipation rates were calculated.The numerical simulation show the variation law of flow patterns and velocity in the river,and the research results verify the engineering design scheme and provide technical support for the engineering design.
