摘　　要：来流风绕过输电线路后,将对其产生升力和阻力。笔者采用经典的基于特征线分裂的CBS有限元法进行数值求解,并借助Matlab语言编程仿真模拟了该过程。得到了雷诺数为100时输电线路的升力和阻力系数,以及漩涡脱落过程,为进一步研究自激振动等更加复杂的非定常流动问题奠定了基础。The wind coming around transmission lines will produce lifting force and resistance. This paper adopts the classicalCBS finite element method based on characteristic line splitting and simulates the process by Matlab language programming.The lifting and resistance coefficients of the transmission line and its vortex shedding process at the Reynolds number of 100are derived in this paper which lays a foundation for further study on the self-excited vibration and more complex unsteadyflow problems.
