基于有限元方法对鲆鲽网箱耐流特性的数值模拟
Numerical Simulation for the Anti-Current Characteristic of Flatfish Cage Based on FEM
摘要
Abstract
Flatfish cage in sea may move and deform under the effect of current, It is necessary to carry out transient dynamic analysis for cage configuration for the safety of flatfish.Herein, a numerical model based on finite element method(FEM) is developed, and then the whole displacement of flatfish cage assembled square mesh net and support pipe in bottom border is calculated, The simulation results show that the shape of cage net changes greatly, and the horizontal and vertical displacement of bottom border increase with the growth of flow velocity.Nevertheless, the bottom border of fish cage can keep level position, and it dosen't incline obviously all the time.Therefore, it can be found that this kind of flatfish cage has good anti-current characteristic.关键词
