Experiment and simulation study on relationship between diameter of high-pressure water abrasive jet nozzle and cutting capacity
Guilin University of Electronic Technology, Guilin. Guangxi, China
High pressure water abrasive jet nozzle is key part of the particles acceleration. The diameter of nozzle has important effect for jet fluid. Through experiment and simulation explore the relationship between nozzle diameter and jet fluid cutting capacity. The result indicate: ①the cut depth and broad reduced in linearly relationship with the diameter of the jet nozzle. ②In same pressure, decrease the nozzle diameter will reduce the cutting ratio energy; ③The acceleration and attenuation of the nozzle axial flow in different diameters are basically consistent, The smaller nozzle diameter, The flow acceleration will slower, the attenuation will faster, the is velocity core segment will shorter and the cutting ability will lower;Consider from energy consumption, cutting efficiency and other factors, for common material cutting the nozzle preferred diameter is: 0.6~1.0mm, it’s unfavourable to select the 0.2mm diameter
