考虑流和内波影响的航行体兴波破冰数值研究
Numerical study on wave-making and ice-breaking of vehicle considering influence of current and internal wave
摘要
Abstract
To address the unclear mechanisms of how oceanic currents and seawater density stratification affected the wave-induced icebreaking capability of underwater vehicles,based on the computational fluid dynamics-discrete element method(CFD-DEM),a multi-medium coupled numerical model of underwater vehicle-layered ice-homogeneous current and density-stratified fluid was established.Systematic simulations of the wave-induced ice-breaking process were conducted under multiple parametric combination conditions including different current conditions,density stratification intensity,navigation velocity,and submergence depth.The ice-breaking effectiveness was evaluated through the ice damage ratio and the number of ice fragments.Research results show that for the considered ice thickness,a critical velocity exists for wave-induced icebreaking by the underwater vehicle,near which the ice damage effect is most severe;under dynamic current conditions,following currents inhibit the wave-making of the vehicle,and the ice fragments tend to be coarser,so the icebreaking effectiveness is reduced;head-on currents promote the wave-making of the vehicle,making the ice fragments finer and their size distribution more concentrated;under supercritical internal Froude number conditions,compared with homogeneous fluid,when the vehicle moves inside and below the density stratification,the density stratification inhibits the propagation of internal waves,thereby reducing the degree of ice damage;when the vehicle moves above the density stratification,the influence of density stratification on ice damage is relatively small.关键词
