外文摘要：This study systematically investigates the hydrodynamic characteristics of a fully submerged horizontal cylinder under regular waves, with a focus on two typical forced rotation modes: unidirectional and harmonic rotation. Based on the viscous flow theory, a numerical wave tank model for simulating wave interaction with rotationally forced cylinders has been established using OpenFOAM, incorporating the overset grid technique. The effects of incident wave amplitudes, rotation rates, and rotational angles on hydrodynamic forces are systematically examined, and the force characteristics and evolution laws of the forced rotating cylinder in wave fields are comprehensively compared across all tested conditions. By analyzing the local vorticity, pressure fields, as well as the surface pressure distribution characteristics around the cylinder, the findings elucidate the viscous mechanisms governing the hydrodynamic forces on the cylinder under different rotation modes. Results demonstrate that rotation direction and rate significantly alter the horizontal and vertical hydrodynamic forces. Furthermore, rotation rate heavily influences higher-order harmonic forces on the unidirectionally rotating cylinder, but has a negligible effect on those on the harmonically rotating cylinder. The distinct differences in hydrodynamic forces on the cylinder under different rotation modes are attributed to the varying characteristics of the body-attached vortex motions around the cylinder.
