船舶尾浪数值计算可以辅助评估船舶的尾浪性能,优化船舶的船体形状和运行参数,提高航行性能和燃油效率,也可以用于预测船舶尾浪对其他船舶、港口和海岸线的影响,帮助船舶运营者和港口管理者做出合理的决策,确保船舶运行和港口安全。本文介绍一种广义边界元法的流体动力学分析方法,通过建立高速排水型船舶的控制方程,并在有限元仿真软件Fluent中进行了高速排水型船舶的尾浪数值计算和仿真。
Numerical calculation of ship′s tailwave can assist in evaluating ship′s tailwave performance, optimizing ship′s hull shape and ship operation parameters, improving ship′s navigation performance and fuel efficiency, and can also be used to predict the impact of ship′s tailwave on other ships, ports and coastlines, helping ship operators and port managers to make reasonable decisions and ensure ship operation and port safety. In this paper, a generalized boundary element method for fluid dynamics analysis is introduced. By establishing the governing equation of a high-speed draining ship, the numerical calculation and simulation of the tail wave of a high-speed draining ship are carried out in the finite element simulation software Fluent.
