| 摘 要： | 利用VOF模型,非稳态气、液多相流的N-S方程,采用有限体积法、结构化与非结构化混合网格和单机多核并行运算技术,数值模拟了喷射虹吸式坐便器冲水过程的三维三相流动。对排污管的驼峰顶断面的清水、污水、空气三相的体积分数积分数进行了定量计算,分析了虹吸过程的气、液状态分布及求解域中各相的体积积分数。对喷射虹吸式坐便器形成虹吸现象的水力特性实现了预测,为坐便器的设计提供了理论依据。

| Abstract: | With the finite volume method and mixed structured and unstructured grids,the VOF Model is adopted to close the unsteady N-S equations for the gas liquid Multi-phase flow using parallel computing on multi-core computer technology.The 3D three-phase flow field in flushing process of siphon jet toilet is numerically simulated.The fractions of clean water,sewage,air on surface of trap crest are quantitative calculated,and the gas-liquid state distribution in siphon phenomenon process and three phases fraction ... |
