Numerical analysis of bilge keels effects on the rolling motion of a ship

摘要：

　　It is a huge challenge to accurately simulate rolling motions of ships due to the tremendous effect of viscosity.In this paper, the simulations for rolling motions of the 3D ship models DTMB5512 with and without bilge keels were carried out by naoe-FOAM-SJTU solver based on OpenFOAM.The naoe-FOAM-SJTU solver utilized the Reynolds Averaged Navier Stokes (RANS)method.The results of free decay rolling motions were compared with the experimental data to ensure the reliability of the calculations, and the results showed that the bilge keels increased the natural period and reduced the roll angle for free decay rolling motions.For forced rolling motion, the results showed that bilge keels reduced the maximum of the damping moments.
