摘　　要：根据立式超声波洗瓶机的工作原理,在分析竖壁上水滴相关参数的基础上,求得西林瓶内壁上小水滴所受的各个力的大小,并得到吹落水滴所需的最小空气流动速度。通过GAMBIT建立7mL西林瓶内壁模型并划分了精细的网格,运用Realizable k-epsilon两方程模型,利用FLUENT软件模拟了喷管气冲时瓶内的流场,得出了洗瓶机气冲时为吹落7mL西林瓶内壁水滴所需的喷管最佳位置、内径以及与之相对应的喷管中的最小空气流速。According to the working principle of vertical ultrasonic vial washing machine,receiving respective force of small water droplets on the inside wall of vials and the minimum air velocity of blowing off water droplets can be obtained based on the analysis of water-droplet-related parameters.The inside wall model of 7mL vial created by GAMBIT was divided into fine grids.Then the Realizable k-epsilon Two Equation Turbulence Model was adopted and the flow field of vial by FLUENT software was simulated when air was flushing inside the wall.In that case,the optimal position,inner diameter and the corresponding minimum air velocity of needle can be acquired to meet the needs of vial washing machine applied to 7mL vial.
