Performance of a Magnus effect-based cylindrical roll stabilizer on a full-scale Motor-yacht

Abstract

Abstract The rotor stabilizer systems based on the Magnus principle are among the alternative systems used as an anti-rolling system. The key objective of this paper is to extensively study the performance of the Magnus stabilizer on a ship's roll-heave motions in a regular beam sea and at low velocity, as well as to investigate the hydrodynamic characteristics of the rotating cylinder in the varied diameters and rotation speeds. Two-dimensional rotating cylinders and three-dimensional ship-rotor cases are simulated using the RANS solver by adopting SST k-ω turbulence model. Flow past a rotating cylinder is computed with cylinder diameter-based Reynolds Numbers of 7.33 × 105, 1.01 × 106 and 1.26 × 106 in the spin ratio range of 1.52
