| 摘 要： | 对空化射流抛光喷嘴的流场整体进行了仿真分析.对锥形射流喷嘴与旋转射流喷嘴的流场进行模拟计算,得到流场中速度与压力分布图,工件表面处速度和压力都呈现M形分布.旋转射流因为具有旋转速度而有更好的掺混能力,空化能力更强.综合比较,旋转射流喷嘴更适合空化射流的应用.

| Abstract: | Cavitating liquid jet machining nozzle flows was simulated and analyzed.Cone-shaped jet nozzle and swirling jet nozzle flow field distribution characteristics were compared.Axial velocity met the maximum value near the nozzle outlet and decreased.Velocity and pressure were both appeared M form on the workpiece surface,so the removal functions were M form.Swirling jet had better turbulent blending and cavitating capacity due to the tangential velocity.The swirling jet nozzle was more suitable for cavitating ... |
