Abstract: Simulation analysis and experiments are performed to investigate the influence of the concentration of abrasive particles on the processing quality of abrasive flow in mesoscopic scale. Both analysis and experimental results show that with the increase in abrasive concentration, the dynamic pressure and turbulent kinetic energy increase, and the grinding effect is enhanced. The shapes of grinded workpieces are measured by zoom non-contact 3D measurement and scanned by SEM, and the results are similar to that of simulation. In other words, with the increase in abrasive concentration, the workpiece roughness decreases, the hole quality and workpiece performance are improved, the workpiece surface quality is enhanced.

Key words: machinery manufacturing technology and equipment, mesoscopic scale, abrasive concentration, simulation analysis
