摘要
对湍流运动的几个基本理论问题作了一定程度的探讨。并根据湍流动能方程分析了大气边界层湍流产生和发展的能量机制,以此为判据推导出了湍流运动的尺度范围和物理含意较为清楚的混合长表达式。
In this paper,some problems of turbulent basic theory are discussed. According to the turbulent kinetic energy equation,mechanism about production and development of atmospheric turbulence of boundary layer is analysed. From this,the extent of turbulent motion scale,and turbulent mixing length expression which has a clear physical meaning are derived.
