Abstract:

在水下智能机器人(AUV)方案设计阶段,针对如何在主尺度和巡航速度确定的前提下得到直航阻力最小的回转体形状这个问题,以Myring型回转体为研究对象,利用计算流体力学(CFD)方法计算其在水中做匀速直航运动时的阻力并与试验值比较以验证准确性。分别对二维和三维2种网格形式,标准和加强2种壁面函数的计算精度和计算效率进行了对比,并在此基础上探讨单独改变艏部或艉部形状时阻力的变化规律。再利用EXCEL、ICEM、FLUENT建立优化平台,基于多岛遗传算法在限制条件范围内对Myring型回转体参数进行全局寻优,寻找不同流速时阻力最小的Myring型回转体,为AUV设计阶段的阻力性能预报和艇型优化提供参考。
