Fundarmentalof two-phase flow s1 10-2 Summary of two-phase flow So called phase is existing form for matter. Generally, there are three phases solid, liquid and gas. Mixed flow of any two or more phases infusible matter called multiphase flow Multiphase flow is common phenomenon in nature, daily life and many project Such as cloud, fog, rain and snow phenomenon dirt in atmosphere, sand in river blood flow in organism; engine burning in boiler, generate electricity refrigerate, vaporize in distil flow in congeal cycle, oil, mine and transportation of natural gas, matter flowed in all kinds of stove pagoda in chemical production; mill run in mining industry, removing dirt in environment defense and so on 7
7 So called “phase”is existing form for matter. Generally, there are three phases solid,liquid and gas. Mixed flow of any two or more phases infusible matter called multiphase flow. Multiphase flow is common phenomenon in nature,daily life and many project.Such as cloud,fog, rain and snow phenomenon;dirt in atmosphere,sand in river blood flow in organism; engine,burning in boiler, generate electricity, refrigerate, vaporize in distil ; flow in congeal cycle, oil, mine and transportation of natural gas，matter flowed in all kinds of stove , pagoda in chemical production; mill run in mining industry, removing dirt in environment defense and so on. §10-2 Summary of two-phase flow
祖流动 §10-2两相流动概述 所谓“相”是指物质存在的形态。通常有固、液、气三 相。任何两相或两相以上不相溶物质的混合流动,统称为多 相流动。多相流动是自然界、人类日常生活和许多工程中常 见的流动现象。如自然界的云、雾、雨、雪现象,大气中的 烟尘、水流中的泥沙、生物体内的血液流动、发动机、锅炉 中的燃烧、发电、制冷和蒸馏过程中的蒸发、凝结循环系统 中的流动,石油、天然气的开采和输送,化工生产中各种炉 塔中物质的流化,采矿工业中的选矿,环保工业中的除尘 等等。 8
