Abstract

Abstract: Numerical analysis of the wind forces acting on a floating LNG platform and an LNG carrier models is performed with a computational fluid dynamics (CFD) code and compared with experimental results obtained in a wind tunnel. The results are represented in the form of coefficients of the wind force components in X and Y directions and yaw moment for various angles of wind attack. The numerical study based on a CFD code started by performing several tests with different type and resolution of the mesh. The results were also compared with two empirical methods as well as additional experimental measurements of similar LNG carrier. Reasonable agreement of the numerical and experimental results was reached. Highlights: CFD analysis of the wind forces acting on a floating LNG platform and an LNG carrier models is performed. The results are compared with experimental results obtained in a wind tunnel. The results are the coefficients of the drag, lift and yaw moment for various angles of wind attack. Experimental measurements over predicted the numerical results in some angles of incidence. Experimental measurements showed a similar dependency with the angle of attack.
