| 摘 要： | 将一种由典型的方尾流动物理模型(水流沿方尾下缘切向脱体)导出的数值方尾边界条件应用于高速多体船兴波问题计算。兴波波形与兴波阻力的数值计算采用基于非均匀有理B样条的广义高阶面元法,所得到的高速双体船算例与高速三体船算例的计算结果合理。

| Abstract: | A transom-stern boundary condition,derived from the typical physical model for transom-stern flow,was applied in the numerical computations for the wave-making resistance of the high-speed multi-hull ships.A generalized higher-order panel method based on NURBS(non-uniform rational B-splines) was employed to calculate the wave pattern and wave-making resistance.The numerical results of high-speed catamarans and tri-marans were considered reasonable. |
