摘　　要：为解决舰船尾流场在实验水池模拟测试问题,增强学生对舰船尾流特性的直观理解和认知,研发一种基于照度的舰船模拟尾流测试系统。构建一种将舰船尾流气泡场和湍流场有机融合的新型舰船尾流模拟方案,实现在对舰船气泡尾流场初生、扩散、消失全生命周期要素模拟的基础上,根据流场中气泡数量和尺度会使光的透射信号产生显著区别这一特点,开发一种基于照度的舰船模拟尾流测试系统。通过实验测试及与声尾流测试系统测试结果相互验证,证明了基于照度的舰船模拟尾流测试系统的可行性和有效性。In order to solve the test problem of ship wake field simulation in towing tank and enhance the students’ intuitive understanding and cognition of ship tail characteristics,a ship simulation tail flow test system based illumination is developed.For the ship wake simulation and test problems in towing tank,a new ship wake simulation scheme that organically integrates the ship wake micro-bubble field and the turbulent field is designed to simulate the full life cycle elements of the emergence,diffusion and disappearance of the ship bubble wake field.For the number and scale of bubbles in the flow field distinguish the transmission signal of light significantly,an illumination-based ship simulation wake test system is designed and developed.The feasibility and effectiveness of the ship simulated wake test system are proved by the experimental test results.
