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.
In order to study the performance and application conditions of booms in typical structure, based on the NS equation and VOF of incompressible viscous fluid, CFU commercial software Fluent was used to conduct numerical experiments on the oil-retaining performance of the typical booms. And verified the physical experimental process under the same experimental conditions.Under different water flow velocities, the maximum intercepting capacity of the single booms and the double booms was compared and analyzed.The results showed that the double booms could enhance the oil displacement Effect, the relative rate of increase increases with the flow rate increases; at low flow rates, the use of double body oil boom is of little significance.In practical applications, booms have their applicable conditions, and when the oil spill size or flow rate exceeds the critical value Boom failure.
