高速船舶的波浪增阻特性分析和船型优化设计

Analysis of wave drag increasing characteristics and ship shape optimization design for high speed ships

高速船舶的航行过程中,海风和波浪阻力会增加船舶的能耗,不利于船舶的高速、稳定航行,因此,基于流体动力学的高速船舶波浪增阻特性研究成为一项热点。本文通过建立波浪基本理论,结合高速船舶的流体动力学模型和CFD有限元仿真软件,对高速船的波浪增阻特性进行建模,并对不同型线设计的船舶进行了CFD有限元仿真。

During the sailing of high-speed ships, sea breeze and wave resistance will increase the energy consumption of ships, which is not conducive to the high-speed and stable sailing of ships. Therefore, the study on the wave-drag increasing characteristics of high-speed ships based on fluid dynamics has become a hot topic. In this paper, by establishing the basic theory of waves, combining the fluid dynamics model of high-speed ships and CFD finite element simulation software.The wave-drag increasing characteristics of high speed ships are modeled and CFD finite element simulation is carried out for ships with different profile designs.
