摘　　要：时空守恒元和解元方法(CE/SE)是一种高精度的数值求解方法。采用改进的CE/SE方法和并行分区技术,针对非结构网格,发展了一套求解二维Euler方程的并行程序。对NACA0012翼型的亚跨声速流动和多段翼型复杂绕流进行了分区并行求解,多区并行计算的结果与实验的结果吻合较好,表明了本文研究方法的正确性和有效性。同时文中的分区方法能实现各处理器之间的负载均衡,有效地节省计算时间。The Space-Time Conservation Element and Solution Element （CE/SE） method is a high-resolution numerical method. The improved CE/SE method and a suitable parallel domain decomposition strategy had been used to develop the parallel program for solving the Euler equations, based on the unstructured grid. Some standard test cases that contained NACA0012 airfoil in subsonic and transonic flow and multi-element airfoil in low speed flow are computed and compared with experimental data to demonstrate the accuracy and effectiveness of the method. At the same time, the parallel domain decomposition method here can achieve load balance among computing nodes, and save computational time effectively.
