摘要
本文采用粘性CFD方法,在Fluent商业软件平台上研究沿海航标工作船中部若干典型横剖面在设计状态下进行强迫横摇运动的水动力特性。通过获取强迫横摇运动下所受到的横摇力矩,由拟合方法求解出这些典型横剖面在安装或不安装舭龙骨情况下的横摇附加阻尼,进而评估加装舭龙骨装置以减少船舶横摇运动的效果。
With the commercial software Fluent, the viscous CFD method is employed to study the rolling hydrodynamic characteristics on several typical sections of the coastal navigation mark ship which is assumed in the forced rolling motion. According to the rolling moment obtained from the forced rolling motion, rolling damping is obtained through the numerical fitting approach for the typical sections, where the sections would be taken with bilge keel installed or not installed. Finally, the reduction of rolling effect is assessed by the installation of bilge keel.
