本文提出了结合通量校正输运（FCT）算法的有限元法（FEM）作为模拟流光电晕的方法。用非结构化网格对感兴趣区域进行离散化，并计算了两种模型的流传播过程，以说明所提方法的性能。与传统的有限差分法（FDM）与FCT相结合的方法相比，该方法所需要的网格数量要少得多，而基于结构化网格的FDM-FCT方法所得到的拖波传播现象也非常相似。
This paper proposes the Finite Element Method (FEM) combined with Flux-corrected Transport (FCT) algorithm as a method to simulate streamer corona. The interested region is discretized with unstructured grids and the streamer propagation processes of two models are calculated to illustrate the performance of the proposed method. The proposed method requires substantially smaller number of grids than the conventional method-Finite Difference Method (FDM) combined with FCT, and the appearance of streamer propagation is quite similar to that of the papers which used the FDM-FCT method based on the structured grids.
