摘　　要：为研究典型结构围油栏拦油性能及适用条件,基于不可压缩黏性流体的N-S方程和流体体积分数方法(VOF),利用CFD商业软件Fluent对典型结构围油栏拦油性能进行数值实验,并验证了同一实验条件下的物理实验过程.在不同水流速度下,对单体围油栏和双体围油栏最大拦油能力进行比较分析.结果表明:双体围油栏能够提升围油效果,相对提升率随流速增加而增大;在低流速时,使用双体围油栏意义不大.在实际应用中,围油栏具有其适用条件,并当溢油规模或流速超过临界值时,围油栏失效.To analyze the performance and applicable conditions of the typical oil boom,the interception of typical oil boom was simulated by using the CFD software Fluent based on N-S equations of incompressible viscous fluid and volume of fluid（VOF） method,and the physical processes were validated successfully under the same experimental conditions.The containing capabilities of the monomer oil boom and the double oil boom at different water velocities were analyzed,and results show that the double boom can enhance the effects of oil interception,whose related upgrade rate grows as the water velocity increases.When the water velocity is low,the double oil boom makes little sense.The oil boom has certain applicable conditions in practical applications,but the oil boom fails to work when the critical quantity or current velocity is exceeded.
