The analysis shows that with given grid size higher accurate difference scheme can give higher resolutions with wider range of scales, or with given accuracy large grid size can be used for the higher accurate difference scheme. The second part is the numerical simulation of two-dimensional axisymmetric jet. The simulation results show the structure in the near field and the initial transition. In the near field, Kelvin-Helmholtz instability leads to the formation of vortex ring, and nonlinear growth leads to the merging of vortex ring. This is the main instability form. Under the assumption of axisymmetry and two-dimensional computing conditions, the results are applicable only in the near field.

第二部分采用高精度的差分格式对二维轴对称射流进行了数值模拟，模拟结果显示了射流流场结构和涡结构的发展过程，在射流流场近区，K-H失稳导致涡环的产生以及非线性效应的增长导致涡环的对并是射流失稳的主要形式；分析指出在轴对称假设下的射流数值模拟只适用于射流近区的分析。

The model of 3-dimensional stretching vortex ring of turbulent elliptic jet in crossflow are discovered for the first time. It is pointed out that in the evolution of turbulent jet in crossflow the 3D vortex rings, which stretching, distorting, swing in transverse direction and twisting around the stream-wise, play the leading role in the large-scale coherent structures. The counter-rotating vortex pair observed in the literature is in fact the head of the 3-dimensional vortex ring.
