摘要: 目前, 中央热水工程向大型自动化和人性化方向发展, 工程恒温热水混合器应运而生, 它是供水系统专门配套的全自动洗浴水温控制设备。运用C F D软件的RNGk - ε湍流模型对冷热水混合器进行三维数值模拟, 研究其内部流场和温度场的变化情况, 同时分析了入口直径、 入口速度、 入口热水温度等因素对混合器内的流场分布及混合效果的影响。研究结果反映了混合器内部的复杂流动, 为混合器的设计和改进提供了理论依据。

关键词: 冷热水混合器, 流场, 温度场,  , C F D软件, 数值模拟

Abstract: Presently, the constant temperature hot water mixer was produced, because the central hot water engineering was developing towards largescale automation and humanization. The mixer was automatic temperature control equipment, which was the supporting facility of water system. RNG kε turbulence model in CFD software was used, and threedimensional numerical simulation was carried out on the hot and cold water mixer. The flow field and temperature field were analyzed, and the influence of inlet diameter, speed, and temperature on flow field distribution and mixing effect was found out simultaneously. The results could truly reflect the complex flow in the mixer and provide a theoretical basis for studying deeply about the design and improvement of mixer in the future.

Key words: Hot and cold water mixer, Flow field, Temperature field, CFD software, Numerical simulation
