摘要：
In this paper, for the purpose to get more quantified information, such as the scale of vortex, a biorthogonal wavelet function bior5.5 with 4-layer decomposition is used on the velocity field measured by PIV. The vorticity field and swirling strength field corresponding to reconstructed velocity fields in each different layer can be calculated. By the above method, the velocity field of an impinging jet was analyzed. The distributions of large and small-scale structures, as well as their kinetic energy distribution were obtained.
