This paper presents a numerical study on focused wave and current interactions with a cylinder.The cylinder is moving in the opposite direction to the wave propagation.An effective computational decomposition method is adopted to reduce the calculation resources.A potential solver high-order spectral(HOS)method is applied to generate focused wave field,while our in-house computational fluid dynamics(CFD)solver naoe-FOAM-SJTU with overset grid takes the charge of achieving the viscous effect around the moving cylinder.The viscous domain moving with the cylinder thus the size and mesh grids in computational domain is greatly reduced.The pressure on cylinder surface and wave fields around cylinder are compared with experimental data,shows a well agreement.Meanwhile,the scattering wave field and vortex shedding are discussed.With the existence of moving cylinder,the classical scattering wave types are still observed. 展开更多
