给了光滑壁界附近湍流平均运动速度分布对数律的一点修正;以某些实验曲线进行了检验并加以分析,特别指出了,经典对数律不能描述完整的湍流核心区,而经过修正后才可能真正描述完整的湍流核心区。
A little correction of the logarithm law of the average velocity distribution of turbulent flow near the smooth wall is given. Some experimental curves are tested and analyzed. In particular, the classical logarithm law can not describe the complete turbulence core region, and after being amended It is possible to truly describe the complete turbulence core area.
