壁湍流标度律的实验研究

摘要

A turbulent boundary layer along a flat plate with zero pressure gradients has been explored in a wind tunnel. Longitudinal velocity measurement at different vertical location has been carried out using hot wire anemometer. The scaling law of the nth order structure function of the velocity increment has been analyzed.%对风洞中零压力梯度平板湍流边界层进行了实验研究，用热线风速仪测量了不同法向位置的脉动速度，研究了平板湍流边界层不同法向位置速度结构函数的标度律。
