摘　　要：以KCS为研究对象,利用CFD计算软件STAR-CCM+,计算不同尺度下KCS船伴流场的分布情况,分析尺度效应对船舶伴流场的影响。为修正由尺度效应引起的模型尺度与实尺度船模船艉标称伴流场的误差,借鉴智能假体模型(SDM)的概念,并通过软件Friendship中的Framework模块对原模型的艉部进行修改,讨论不同收缩程度的艉部变形对修正伴流场尺度效应的作用。结果表明:SDM方法对修正伴流场尺度效应的作用效果明显,且通过模型尺寸的收缩变形基本可以达到目标伴流场的伴流分布形式。In this article, different scales of KCS ships are studied with the CFD software STAR-CCM＋ in order to analyze the influence of the scale effect of the ship wake field. To correct the error caused by the scale effect, the concept of Smart Dummy Model （SDM） is taken as reference. Based on the module of Framework imbedded in the CFD code Friendship, various degree of contraction deformation on after-bod- ies is created for better analysis results. It is seen that the method of SDM is applicable in solving the problem of scale effect of the wake field, and the model-scale wake field successfully meets the target wake field distribution of the full-scale one through the deformation of stern.
