本文提出了一种用一维湍流实验数据研究涡流管的方法。涡管被检测为局部最大值的小波变换的速度数据的尺度空间图。然后,可以提取典型的速度模式。风洞试验结果与三维直接数值模拟结果一致。
This paper proposes a method to study vortex tubes in one-dimensional velocity data of experimental turbulence. Vortex tubes are detected as local maxima on the scale-space plot of wavelet transforms of the velocity data. Then it is possible to extract a typical velocity pattern. The result for data obtained in a wind tunnel is consistent with those of three-dimensional direct numerical simulations.
