摘要
基于水射流冲击模型,应用FLUENT流体分析软件对喷嘴射流冲击力数值模拟和仿真,得出不同的射流压强、喷距及喷嘴出口直径对射流冲击力及冲击作用区域的影响。结果表明:其他相关因素确定时,射流冲击力随着射流压强的增加而增大,随着喷距的增加先增大、后减小;不同喷嘴出口直径的射流冲击力的比值约为喷嘴出口直径的平方比,射流冲击的作用区域与喷嘴出口直径有关,其面积约为出口直径的2.9倍。
Based on water jet impact model,the jet impact numerical simulation and simulation analysis was carried out by FLUENT. The content include the effect of different jet pressures ,jet distances and the diameters of nozzle outlet on jet impact force and area. The results indicate that impact force increases with the increase of jet pressure ,decreases after first increase with the increase of target distance when other related factors was determined. The ratio of impact is approximately equal to the nozzle exit diameter ratio of the square. Jet impact area is related to the nozzle exit diameter ,its area is about 2.9 times of the exit zone.
