Abstract :
With the increasing speed of high-speed train, aerodynamic brake has become an important brake method. In order to make better use of Fluent for high-speed train with aerodynamic brake numerical simulation, this paper mainly discusses about how the three parameters of Cell Ratio, Face Ratio and Neighbors influence the methods of domain decomposition. According to comparing the parallel efficiency and iteration time of Principal Axes, Cartesian Strip, Principal Strip and Principal Z-Coordinate domain decomposition methods, we obviously obtain that Cartesian Strip method has the best parallel efficiency. The result provides theoretical reference for numerical simulation of high-speed train.
