Abstract
An experimental study has been carried out to improve the performance of a commercial abrasive blasting nozzle, by simply redesigning the nozzle's inner contour. The analytical 1-D code, that can evaluate both the frictional effects on the nozzle inner wall and the sphericity effects of the particle, is utilized to calculate the dynamics of the particle inside the nozzle. The analytical results are compared to the experimental ones, that were obtained from images of the particle streaklines downstream from the nozzle exit. It is noted that the particle velocity at the redesigned nozzle exit increases as compared to the original commercial nozzle.
