摘　　要：实尺度船舶快速性数值模拟方法是国内外关注和研究的重点。实船的水动力性能大多是通过模型尺度的结果外推得到的,然而船模不能同时满足傅汝德数与雷诺数相等,且一些外推方法的准确性还有待考证。论文从实尺度数值模拟的尺度效应问题出发,简要介绍船舶数值模拟方面的关键问题,并从网格、湍流模型、时间步长和壁面粗糙度等角度归纳和分析实尺度船舶快速性数值模拟方法的研究现状。基于研究现状,提出尚需进一步解决的问题。该文旨在介绍目前实尺度船舶快速性的研究进展,希望为今后船舶水动力性能研究提供参考。Numerical simulation of full-scale ship resistance and propulsion performance has been paid much attention at home and abroad.Hydrodynamic performance of a full ship is usually extrapolated with the result of the model scale.However,a ship model can’t satisfy the equivalence of Froude number and Reynolds number simultaneously,and accuracy of various extrapolation methods still needs to be verified.Starting from the scale effect in the full-scale numerical simulation,this article introduces key issues in the ship numerical simulation briefly,and summarizes the research status of numerical simulation methods for full-scale ship resistance and propulsion performance from the perspectives of mesh,turbulence model,time step and wall roughness.Some suggestions and problems that need to be solved further are put forward.
