Simulation and selection of fin stabilizers for polar cruise ships based on Computational Fluid Dynamics

Abstract

Polar cruise ships have high requirements for comfort, so it is an important problem to select fin stabilizers matching with the target ship. The underwater movement under the maximum sailing speed and the active anti-rolling of the fin stabilizers under the low sailing speed of an 8035 gross tonnage polar cruise ship are simulated by means of Computational Fluid Dynamics (CFD) simulation, and the hydrodynamic characteristics of the fin stabilizers are explored. The fin type of NACA0012 is selected for the target ship by analyzing the lift and drag characteristics of two common fin types of NACA0012 and NACA0015. The limiting fin angle of fin stabilizers is found to be about 15~20° at the maximum speed and about 30-35° at the low speed. The research results can provide a reference for the design and selection of fin stabilize.
