浮力羽流原理分析与研究进展

Theory analysis and research progress about buoyancy plume inducted by heat source

从解析分析、实验研究和数值模拟三个角度对羽流基本模型的研究历史、发展现状、研究前景进行了总结,重点讨论了羽流速度场和温度场的分布规律,并对影响羽流的一些重要因素如质量流率、浮力通量、卷吸系数、扩散角进行了归纳说明,以期为工业生产和环境保护提供指导。

This paper summarizes the research history,development status and the research prospect of basic plume models based on three angles of analytical analysis,experimental study and numerical simulation.The rules of velocity field and temperature field distributions of plume are emphatically discussed.Some important factors such as mass flow rate,buoyancy flux,entrainment coefficient,the spread angle were also made a summary description,in order to provide guidance for industrial production and environmental protection.
