A Function For Turbulent Fluctution Velocity

本文提出一种描述湍流脉动速度的函数，对该函数的能反映湍流特性的自相似性和频谱进行分析，同时总结出该函数中的参数的变化规律，本文对各向异性湍流的模拟有指导意义。

This paper puts forward a function, which is suitable to describe turbulent fluctution velocity. Self-similar law and fluctution spectrum of the function are analyzed, and the relation among parameters of the functions is discovered in detail. The study is useful for simulating non-isotropic turbulence.
