By studying the autocorrelation function of the probe signal, it is found that the large eddy quasi ordering structure likely exists in near wake, but there is no turbulence in farwake.
结合探针信号的自相关函数，研究流场湍流结构，发现近尾可能存在大涡拟序结构，而在远尾则没有湍流。

The model USES the curved vortex elements on the circular arc as the basic discrete elements for trailed filaments and utilizes the free wake extension to form an adaptive farwake downstream.
