急流型河流围油栏设计与拦油性能优化
Design and Optimisation of Oil Spill Recovery Devices for Fast-flowing River
在处理水上溢油事故中,围油栏发挥着至关重要的作用。针对现有急流型河流围油栏较为单一的问题,依据传统围油栏参数,设计新型双层网栅围油栏,用于急流型河流的溢油回收。基于计算流体动力学(computational fluid dynamics, CFD)中主流计算流体力学软件FLUENT,建立二维数值水槽模型,以多相流法(volume of fluid, VOF)作为计算模型,模拟油水在新型围油栏作用下的瞬态分布,并以拦油量作为监测数据探索围油栏拦油性能优化方向。结果表明优化后的围油栏网格半径为30 mm,孔隙率为0.3。相比于传统围油栏,新型围油栏拦油量优于传统围油栏,为急流型河流围油栏设计提供了有效参考。
Oil booms play a vital role in dealing with oil spills on water. Aiming at the single problem of existing oil booms in fast-flowing rivers, a new type of double-layer mesh fence was designed for oil spill recovery in fast-flowing rivers based on the parameters of traditional oil booms. Based on the mainstream CFD (computational fluid dynamics) software FLUENT, a two-dimensional numerical flume model was established to simulate the transient distribution of oil and water under the action of the new oil containment boom with VOF (volume of fluid) as the computational model, and the volume of oil intercepted was used as the monitoring data to explore the direction of optimizing the oil containment performance of the oil containment boom. Monitoring data was used to explore the optimization direction of oil containment performance of the oil containment boom. The results show that the optimised oil containment boom has a grid radius of 30 mm and a porosity of 0.3. Compared with the traditional boom, the new oil containment capacity of the new oil containment boom is better than that of the traditional boom, which provides an effective reference for the design of oil containment boom for fast-flowing rivers.
