| Popis: | In the past, many kinds of researches have been carried out on fin stabilizer hydrodynamics under static conditions, but many influencing factors have been neglected, which may affect the accuracy of calculation results, reduce control precision of fin stabilizers and anti-rolling effect. In this paper, computational fluid dynamics (CFD) software is used to simulate the NACA0015 fin and simplified hull based on Lattice Boltzmann method (LBM). In the given environment, dynamic simulations of the factors that affect the hydrodynamic of the fin stabilizer is performed and the corresponding results are given. The feasibility of the new method is verified by comparing with the experimental data. Compared with the traditional CFD method, the proposed new method is more efficient and accurate in dynamic condition. The simulation results are corresponding to reality, which can bring some theoretical reference significance for the optimal design of the fin stabilizer. |
