Abstract
In this study, a blasting nozzle was designed based on incompressible flow analysis to clean wide surface of parts used in power plant. The outlet side section of the designed nozzle has a wide bore with a linear shape. After the design, the nozzle prototype was made by three dimensional printing, and the cleaning performance test was performed after mounting it on the blasting machine. The wide bore size obtained after the analysis was almost the same as the wide bore size obtained from the surface of the plate specimen after the experiment. Ultimately, it was confirmed that the design of blasting nozzle for wide surface treatment is effective.
