摘要
本文简述了用热线风速仪测量“NACA 63-012”对称翼型近场尾流及后缘边界层流动特性,讨论了流场的时均特性及雷诺应力等湍流量的分布特性,提出了无因次速度分布的半经验公式、相关参数及相关曲线解析式,并得出了几点重要结论。
This paper describes the trailing edge and near wake flow of a NACA 63-012 symmetric airfoil measured by a hot wire anemometer. The distribution of mean flow velocity and Reynolds stress is measured and discussed. The semiempirical relation of nondimentional velocity distribution is obtained. Some correlation parameters and ana-lytical correlation functions are also obtained. At last, some importantconclusions are given in this paper.
