网衣对混合结构养殖船内外流场影响的数值研究
Numerical study on the flow field influence of netting on the inside and around of mariculture ship with hybrid structure
摘要
Abstract
Aiming at the distribution of the flow field around the mariculture ship with hybrid structure,the CFD(computational fluid dynamics)method based on the RANS(Reynolds-averaged Navier-Stokes)equation was used to calculate the flow field around the mariculture ships which were without net,with side nets only and with both side and bottom nets.The porous media model was adopted to model the nets in the calculation.Based on the calculated results,the variation of total resistance of the ships with different velocities and the effect of the nets on the flow fields of the ships were discussed.Results show that the total resistance of the ship with side nets is the highest and the total resistance of the ship with both side and bottom nets is the lowest under the same velocity.Vortices appear in the middle compartment of the ship with the presence of side nets,while local blockage inside the ship appears with the presence of both side and bottom nets.关键词
