摘　　要：运用CFD软件对在不同入射角度下的带钢清洗流场特性进行仿真分析,重点研究入射角度对流场速度和带钢表面压力的影响。仿真结果表明,带钢表面速度和压强随着入射角度的增大而增大;当入射角度α=60°时清洗性能最佳。通过仿真可以为高压水射流清洗工程应用提供一定的依据。Based on commercial computational fluid dynamics（CFD） software package, the flow characteristics of strip cleaning working in different incidence angle were investigated through simulation. The effects of incidence angle on speed of flow field and pressure of strip surface were mainly studied. The results indicated that the speed of flow field and pressure of strip surface get wider as the incidence angle gets wider; the cleaning performance with incidence angle of 60° is the best. The study offers references for the application of high pressure water jet cleaning engineering.
