| Abstract: | 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. |
