截击机广泛应用于平艇，但很少应用于深v艇。本文重点研究了截流器对深v型容器周围粘性流场影响的一般规律。设计了一系列不同死角的简化深v形容器，计算了它们在六自由度约束下的升力。通过不同网格尺寸条件下的数值结果与实验数据的对比，建立了一套数值模拟方案。然后，采用CFD方法模拟了不同截流器高度、死角和速度条件下深v型船周围的粘性流场，分析了阻力、升力、底部波浪剖面和压力分布以及船尾速度分布的结果。结果表明，鸡尾流的虚长、虚高、底部压力分布、升力系数与速度和拦截器高度成正比，但在速度和拦截器高度相同的情况下，增大死升角会减小；当深v型船的运动受到约束时，截流器无法减小阻力。在某些特殊条件下，会诱发一个连续的分布涡，并在其前方发现另一个小尺度涡。
Interceptor is widely adopted by planing boat but adopted by deep-Vee vessel rarely. This study focuses on the general rules of the influence caused by interceptor on the viscous flow field around deep-Vee vessel. A series of simplified deep-Vee vessels of different deadrise angles are designed, and the lift force of them are calculated in the condition that six-degree of freedom is constrained. A set of numerical simulation scheme was established through the comparison of the numerical results and experimental data in the conditions of different mesh sizes. Then, the viscous flow field around the deep-Vee vessel in the conditions of different interceptor height, deadrise angles and velocities are simulated by CFD approach, the results of drag, lift force, wave profiles and pressure distribution on the bottom and velocity distribution at the stern are analyzed. According to the results, the virtual length, height of rooster tail flow, pressure distribution on the bottom, lift force coefficient were proportional to velocity and interceptor height, but decreased when the deadrise angle is increased in the condition of the same velocity and interceptor height. The resistance cannot be reduced by interceptor if the motion of the deep-Vee vessel was constrained. A continuous distributed vortex was induced, and another vortex of small scale was found located ahead of it in some special conditions.
