摘　　要：基于CFD技术开展滑行艇阻力计算,分析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表面的气液分布情况。合理的参数设置可以使数值计算结果与试验结果较好地吻合,证明了基于CFD技术计算滑行艇阻力是可行的。The resistance of planing craft is calculated based on CFD method. The influence of time step and mesh generation near wall to accuracy of calculation are analyzed. The numerical results show that different time step and mesh generation mainly influence the frictional resistance and the volumn fraction of water on the surface of hull bottom. Reasonable parameter setting can make numerical results fit well with the experimental results, which proves the calculating resistance of planing craft based on CFD is feasible.
