中文摘要:
      基于CFD技术,以排水型高速船Model 5b为模型,寻求改善高速船阻力性能的尾压浪板新形式。首先尾压浪板新形式的确定在静水条件下进行,然后在波浪条件下验证该压浪板的阻力性能。基于CFD软件建立三维数值波浪水池,静水条件下采用切割体网格技术预报船模的阻力性能。波浪条件下数值水池入口采用直接造波方法,尾部采用人工阻尼消波方法,自由面采用VOF方法处理,采用重叠网格技术预报船模的阻力性能以及运动响应。确定一种比常规压浪板阻力性能优良的分段式压浪板,为船舶节能附体的研究提供参考。
英文摘要:
      In this paper, a new form of stern flap for improving the resistance performance of high-speed vessels is proposed based on the Model 5b of the high-speed ship model. First, the new type of the stern flap is determined under the condition of calm water, and then the resistance performance of the stern flap is verified under the condition of waves. The 3D numerical wave tank is established based on CFD software, prediction of resistance performance of ship model by using trimmed mesher in calm water condition. The numerical tank inlet use the method of direct wave making under wave conditions. The outlet is set by using wave damping, the free surface is treated by VOF method, and the model"s resistance performance and motion responses are predicted by overset mesh method. Finally, a new type of stern flap with better resistance performance than conventional stern flap is determined, which provides reference for ship energy saving appendages.
