摘　　要：利用Fluent软件研究二维楔形体结构的砰击问题,考虑外部大气压重力以及网格影响等因素,建立二维有限元模型,对不同斜升角的楔形体结构以不同的速度进行等速入水的情况进行计算。研究发现,最大砰击压力随着楔形体斜升角的增大而减小,随砰击速度的增大而增大。By using the simulation software Fluent, the water entry of wedge-shaped sections was studied and a two-dimensional finite element model was built up considering the effect of external atmo-spheric pressure,gravity and mesh quality. The article calculated the impact pressure of the wedgeshaped sections with different deadrise angles on constant velocity. The results show that the water impactincreases with addition of deadrise angles and velocity.
