摘　　要：本文以某型号热镀锌气刀为研究对象,利用计算流体力学(CFD)软件Fluent研究了气刀在工作状态下的气流特性。选取刀唇纵向截面进行二维仿真计算,得到气流在刀唇部位的速度和压力分布云图。同时,建立了系统的三维流体模型,得到了带钢表面气流速度和压力分布情况,为气刀结构优化设计提供了理论依据。Taking a air knife as the research object, the flow characteristics of the air knife on work were analyzed by Fluent. 2-D simulation was carried out along longitudinal section of the air knife lips. The speed and pressure distri- butions of flow on knife lips were obtained. At the same time, the speed and pressure distributions of flow on the face of the strip were obtained by 3-D fluid model. It was the reference for air knife optimizing in the future.
