采用欧拉方程与可压缩涡对模型相结合的数值方法，研究了超音速主流与横向喷流干扰流场的气动特性。喷流横截面用一对反向旋转的可压缩涡来模拟。采用有限元Ｏｓｈｅｒ格式及非结构网格数值求解二维欧拉方程以得到非等熵外流场的气动特性及弓波位置。将欧拉方程数值解结果与可压缩涡对流场解结果相结合以研究喷流的轨迹及喷流横截面的变化。最后给出了数值模拟结果并与工程估算结果进行了比较，表明本文所述方法是可行的。
The aerodynamic characteristics of the turbulent flow fields in supersonic and transversal jets are studied by the Euler equation and the compressible eddy-vortex model. The jet cross section is modeled by a pair of contra-rotating compressible vortices. The finite element method Osher and unstructured grid are used to solve the two-dimensional Euler equation to obtain the aerodynamic characteristics and the bow wave position of the non-isentropic flow field. The numerical solution of the Euler equation and the convection field solution of the compressible vortex are combined to study the jet flow trajectory and jet cross-section change. Finally, the numerical simulation results are given and compared with the engineering estimation results, indicating that the method described in this article is feasible.
