【摘要】 海豚具有良好的流线型外形,还有独特的减少湍流摩擦阻力的方法,其游速在某些条件下可以达到每小时70～100km,远远超过现代潜艇的航速。本研究应用计算流体力学方法对海豚外型的水动力性能进行数值模拟,结合其表面高斯曲率分布信息,分析海豚外型的阻力特性,为潜器线型优化提供良好的基础。更多还原

【Abstract】 Dolphins have streamlined shapes,and there is a unique method to reduce the turbulent frictionai resistance.Their travel speed can reach 70-100 km per hour under certain conditions,far exceeding the speed of the modern submarine.In this paper,the hydrodynamic performance of the dolphin model was studied by numerical analysis.Then this paper analyzed the resistance characteristics of the dolphin shape with the surface Gaussian curvature distribution,providing a good basis for the optimization of the submarine.更多还原
