中文摘要：
为探讨适用于滑行艇全航速段数值模拟的网格划分方法，采用CFD技术研究混合网格在滑行艇阻力数值模拟中的适用性，采用不同数量的混合网格对滑行艇粘性绕流场进行数值模拟，对阻力进行计算，并且对比不同网格数量对计算结果的影响，分析其中的原因，得到了适用于滑行艇阻力数值计算的混合网格。在此基础上采用所得到的网格划分方式对滑行艇全航速段进行数值模拟，并与实验结果进行比较，两者吻合较好。
英文摘要：
In order to get the proper mesh generation method for the planning-hull flow field simulation, the software FLUENT is used in this paper to research the applicability of the hybrid grids. The viscous flow field of the planning-hull is simulated by a series of mesh, and the resistance is calculated. The effect of the grid quantity is analyzed, the reason is discussed, and the best mesh generation method is obtained. The suggested mesh generation method is used for numerical simulation of the viscous flow field of different velocity, and the comparison of the numerical results and the experimental data show good agreement.
