摘要
湍流是极为普遍的流动现象,湍流统计模式是目前预测复杂湍流的唯一工具.本文讨论了Navier Stokes方程与湍流的关系,分析了湍流统计模式的局限性,认为一个好的湍流统计模式应当包含尽可能多的湍流脉动结构信息.
The turbulence is a flow phenomenon existing widely in nature. Its statistical model is the only tool of predicting the complex turbulence flows nowadays. In this paper, the relationship between Navier Stokes equations and turbulence is discussed, and the limitation of statistical model of turbulence is analyzed. It is thought that a good statistical model of turbulence should contain the information of turbulence fluctuation structure as much as possible.
