摘　　要：对目前广泛应用于蛋类企业和养鸡场的蛋壳清洗喷雾系统进行模拟优化,旨在满足蛋壳清洗的同时减少水资源的浪费。利用ICEM软件构建几何模型,使用平面四边形网格对计算区域进行网格划分,并针对喷嘴出口末端和喷嘴外轴线区域采用网格加密技术,得到较为优质的网格。将网格导入Fluent,利用有限体积法进行湍流稳态求解,并在求解时采用VOF两相流模型和TAB液滴破碎模型。结果表明,模拟结果能较好地反映喷水速度与喷水有效半径的关系。利用该尺寸关系,最终得到喷嘴的最佳定位尺寸,从而实现对喷水装置的结构优化。The spray of eggs cleaning system was simulated and optimized,which was widely used in enterprises and chicken farms.The researcher tried to save water and met the command of cleaning.Firstly,the geometry parts were meshed in quadrilateral meshes in ICEM,and mesh encryption was adopted in some special areas,such as the internal wall near the nozzle exit and the axis out of the nozzle.Secondly,the good quality meshes were imported in Fluent,and Finite Volume Method was taken to solve the turbulence problem in steady state.Meanwhile,the VOF and TAB model were also considered in computation.Thirdly,the result of simulation reflected the relationship between velocity and radius of spray well,and this relationship helped controlling the spacing among nozzles.Finally,through analyzing,a more reasonable structure could be derived.
