摘要
分层流水槽实验作为一种便捷有力的研究工具,被广泛应用于大气风环境领域的研究之中。它实质上是一种以相似理论和模型实验技术为基础的缩尺流体实验方法。本文先后对密度分层流水槽模拟层结大气流动的实验原理,密度分层的营造以及流场可视化方法进行了系统的梳理,并总结了其在大气风环境研究中的应用现状。以期通过本文的总结梳理,为密度分层水槽实验的设计和应用提供更加系统高效的指导,同时为密度分层流水槽实验在城市通风领域中的应用奠定理论基础。
As a convenient and powerful research tool, the stratified water tank experiment is widely used in the research of atmospheric wind environment. It is essentially a scaled fluid experimental method based on similar theory and model experimental techniques. In this paper, the experimental principle of density stratified water tank simulating stratified atmospheric flow, density stratification construction and flow field visualization method are systematically combed, and its application status in atmospheric wind environment research is summarized. In order to provide more systematic and efficient guidance for the design and application of density stratified water tank experiments, the paper lays a theoretical foundation for the application of density stratified water tank experiments in urban ventilation.
