Shape optimization and hydrodynamic simulation of a Magnus anti-rolling device based on fully parametric modeling

Ship anti-rolling devices are an essential component of modern vessels. The core the Magnus effect-based ship device is a rotating cylinder, hereinafter referred to as cylinders. In this paper, fully parametric three-dimensional modeling cylinders was performed, and design space dimension reduced using Sobol optimization method while still providing accurate reliable results. generates quasi-random sequences that more uniformly spaced in search can efficiently cover entire solution space. shape study cylinder carried out conjunction with computational fluid dynamics find geometry excellent hydrodynamic performance. Critical parameters include diameters ends length cylinder. flow field characteristics before after were compared. results show there be multiple local optimal values for lift drag within increase decrease drag. effect primarily influences position vortex-shedding separation point at surface deflects wake one side. For optimized distribution pressure velocity significantly different. This research forms basis improving practical application devices.
