摘　　要：为了研究高速滑行艇喷溅特性,基于商业CFD软件FINE/MARINE开展了三维滑行艇模型三自由度运动性能的实时数值预报,完成了航速V=2～7 m/s,重心距离艇尾38.1%L、35.1%L共计12种工况下滑行艇的水动力特性、运动性能与航速之间关系的计算,并与试验数据进行了对比,二者吻合良好。将艇体表面的流体特征信息(速度场、压力场和水气体积分数等)导入自编的后处理程序,对艇体节点空间坐标重新生成非结构网格,给定喷溅的判断条件,自动识别和处理艇体喷溅区形状及喷溅阻力构成,论文提出的喷溅处理方法为揭示高速滑行艇喷溅流动内部机理及防飞溅结构形式设计奠定了基础。Numerical prediction of a high-speed planning craft with 3-dof in still water is developed based on the software FINE/MARINE,in order to examine spray resistance of the craft.Hydrodynamic performance of the craft is investigated for different speeds and positions of the center of gravity,and agrees well with experimental data.A self-compiled program applied in automatic recognition of the spray zone and constitution of spray resistance,which will lay a foundation for research on spray proof structure.
