Numerical simulations explore hydrodynamic performance of fin stabilizers, indicating design improvements for ships.
The hydrodynamic characteristics of fin stabilizers are investigated in this paper. Numerical simulations are conducted via a computational fluid dynamics (CFD) method for a fin stabilizer based on the NACA0018 airfoil, and the influence mechanisms of parameters including perforation size, structural configuration, and perforated chamfer angle on the hydrodynamic performance of the fin stabilizer are systematically analyzed. In combination with model experiments on roll stabilizing fins carried out in a towing tank, the feasibility of the numerical simulation method is verified through comparative testing. A solid theoretical basis for the optimal design of high-performance fin stabilizers is provided by this study, and important engineering application value is obtained for improving the navigational safety and adaptability of ships.
