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.
