摘要

为准确预报超大型油轮风载荷，采用SolidWorks建立某超大型油轮的三维模型.在合理设定计算域及网格划分的基础上，选择适当的边界条件及流体动力学方程，计算不同风舷角下船体的纵向、横向及艏摇风载荷系数，并与Isherwood公式估算得到的风载荷系数进行对比.根据空气动力学原理分析部分风舷角下引起二者偏离的主要因素，重点分析艏摇系数存在明显偏差的原因.分析表明，本文提出的流体动力学方法能够有效提高超大型油轮的风载荷估算精度.

Abstract

In order to accurately predict the wind load of a very large crude carrier (VLCC), a three-dimensional model of VLCC was established by using SolidWorks software. On the basis of reasonable setting of computational domain and mesh division, the appropriate boundary conditions and fluid dynamics equations were selected to calculate the wind load coefficients at longitudinal, lateral and yaw moment under different attack angles, and compared with that of Isherwood formula. The main factors which caused deviation at specific wind attack angle between above two methods were analyzed by using aerodynamics principles, especially the obvious deviation of yaw coefficient. Results show that the proposed computational fluid dynamics method can effectively improve the accuracy of wind load estimation for VLCC.

Key words： very large crude carrier(VLCC); wind load coefficients; Isherwood formula; comparative analysis; aerodynamics
