摘要
为了研究在不同的后体模型情况下,通气超空泡的形态及航行体的形状阻力特性,利用商业CFD软件Fluent6.0,对无后体和四种不同后体模型的航行体进行了通气超空泡数值模拟研究.获得了不同后体模型下,通气超空泡航行体的形状阻力系数变化规律及超空泡形态变化规律,同时获得了速度和通气压力的变化对各种后体模型通气超空泡航行体形状阻力系数及超空泡形态的影响,对开展不同后体模型航行体的通气超空泡试验研究具有指导意义.
In oreder to investigate the characters of shape of ventilated supercavity and form drag of vehicles with various afterbodies, numerical investigation of ventilated supercavity vehicles has been conducted using the commercial CFD software Fluent6.0. The law of form drag coefficient of ventilated supercavity vehicles and shape of supercavity with various afterbodies was acquired. The dependence of form drag coefficient of ventilated supercavity vehicles and shape of supercavity on velocity and ventilation pressure was also obtained. This paper will guide experimental investigation of ventilated supercavity vehicles with various afterbodies.
