【摘要】：拖曳体作为一种水下设备,主要用于水下探测、海底地形勘探.其可以按照具体的需求进行设计,故拥有较强的实用性.组合拖曳体具有多个单体,结构复杂,相互干扰之下使得兴波阻力难以计算.因此以一种拥有水上部分的大型组合拖曳体的设计为背景,借助模型拖曳阻力试验,基于CFD理论,使用Star CCM商业软件,配合笛卡尔网格的离散形式,对水面拖曳体的阻力进行计算.通过与试验阻力值的对比,验证了数值算法的准确性.同时,基于计算结果及设计约束条件,对拖曳体结构外形进行优化,并使用数值方法进行了计算,计算结果表明优化后的拖曳体总阻力值有25%的下降.
[Abstract]:As a kind of underwater equipment, towing body is mainly used for underwater exploration and submarine topography exploration. It can be designed according to specific requirements, so it has strong practicability. It is difficult to calculate the wave-making resistance due to the mutual interference. Therefore, based on the CFD theory, the design of a large composite towing body with a water component is taken as the background, with the aid of the model drag resistance test. Using Star CCM commercial software, with the discrete form of Cartesian grid, the drag of towed water surface is calculated. The accuracy of the numerical algorithm is verified by comparing with the experimental resistance. Based on the calculation results and design constraints, the structure shape of towed body is optimized, and the numerical method is used to calculate. The results show that the total drag value of the towed body decreases by 25% after optimization.
