摘　　要：文中对传统围油栏进行形状优化,应用流体体积分数法(VOF),数值模拟优化后的围油栏对两种不同粘度油类拦油效果;通过分析、比较拦油失效速度、失效时间以及围油栏失效前的栏前受压,说明围油栏形状优化的可行性,以提高围油栏的拦油性能。Floating booms is commonly used to hold back oil spill on water surface,while oil boom failure often occurs in cases of water currents with high velocity.In order to improve the performance of booms,firstly volume of fluid（VOF） method was applied to numerically simulate traditional booms,and then the optimization of oil boom was carried out by changing the structure and shape of booms.Through the analysis and comparison of the block oil failure speed,failure time and the pressure before boom failure,the numerical simulate results indicate that the optimization shape of oil booms are feasible to improve oil spill interceptions.
