Analysis of drag reduction performance of elliptical fairings for wave glider hydrophone communicator

  • 摘要: 针对波浪滑翔器声通机载荷减阻问题,设计水声通信机导流罩,并采用流体力学软件分析确定其设计参数;在直航状态下,仿真得到椭圆导流罩最优轴长比;然后在虚拟锚泊状态下优化其前缘长度;最后通过海上试验验证仿真可靠性。结果表明:相比于圆柱形外形,本文提出的导流罩当截面轴长比为3时,导流罩具有最佳减阻效果;在直线和虚拟锚泊运动时分别减阻82.2%和54%;该研究为低速(雷诺数为3×105)水声通信机导流罩设计和优化提供参考和借鉴。

     

    Abstract: To address the wave glider acoustic communicator drag reduction problem, the hydroacoustic communicator fairing is designed and analyzed using hydrodynamic software to determine its design parameters; The optimal axial length ratio of the elliptical fairing is simulated under the direct sailing condition; then the leading edge length is optimized under the virtual mooring condition; finally, the reliability of the simulation is verified by the sea test. The results show that compared to the cylindrical shape, the proposed fairing has the best drag reduction effect when the axial length ratio of the cross-section is 3; The drag reduction is 82.2% and 54% during linear and virtual mooring motions, respectively; this study provides reference for the design and optimization of the fairing shield for low-speed (Reynolds number is 3×105) hydroacoustic communicators.
