简要介绍FLUENT软件,回顾其在流场计算中的应用。以电站进水口、宽尾墩和阶梯溢流坝、双弯曲型溢洪道3类工程项目为例,叙述该软件在水利工程中的应用情况。针对水利工程问题边界复杂、水气混掺、自由面较多的特点,分析模型建体、自由面处理和网格划分等主要问题,并采用与模拟形状基本相同的体型、网格线与水流方向基本一致、边界位置远离紊动剧烈区域的方法予以解决。数值模拟表明,FLUENT软件可以处理复杂体型和具有多个自由面的水汽二相流VOF模型问题。
Briefly introduce FLUENT software and review its application in flow field calculation. Take the power station inlet, flaring pier and stepped spillway dam, double curve type spillway project as an example, describes the application of the software in water conservancy project. In view of the complex boundary conditions, the mixed water-gas mixing and the large number of free surfaces, the main problems of model building, free surface treatment and meshing are analyzed. The body shape, grid line and water flow Basically the same direction, the boundary position away from violent turbulent area to be resolved. Numerical simulation shows that FLUENT software can deal with the problem of VOF model of two-phase water vapor with complex body size and multiple free surfaces.
