中文摘要:
      滑行艇作为一种高性能船舶,被广泛地应用于军事、运输、娱乐等方面,而滑行艇的阻力性能备受人们关注。本文基于CFD技术开展了滑行艇阻力计算研究,分析了时间步长与近壁面网格划分对计算精度的影响。数值计算结果表明,时间步长和近壁面网格划分的不同主要影响的是滑行艇的摩擦阻力以及艇底的气液分布情况。选择合理的参数设置可以使数值计算结果与试验较好地吻合,证明了CFD技术计算滑行艇阻力的可行性。
英文摘要:
      As a high-performance ship, planing craft is widely used in military, transportation and entertainment. The resistance performance of planing craft has been concerned by people. In this paper, resistance of planing craft is calculated and researched based on CFD method. The influence of time step and mesh generation near wall to accuracy is analyzed. Numerical results show that different time step and mesh generation mainly influence the frictional resistance and the volumn fraction of water and air on the ship bottom. Choosing reasonable parameter setting can make numerical results are in good agreement with the experimental results. The feasibility of calculating resistance of planing craft based on CFD method is certified.
