압축성 유동해석에 기초한 곡면 세정을 위한 브라스팅 광폭 노즐의 설계 및 성능시험 = Design and Performance Test of Wide Blasting Nozzle for Curved Surface Cleaning based on Compressible Flow Analysis

다국어 초록 (Multilingual Abstract)

In this study, the blasting nozzle for surface treatment of the curved surface of parts in powerplant industry was designed and the cleaning performance was examined through the compressible flowanalysis. At this time, the outlet of the curved nozzle was designed as a curved surface along the surfaceof the part. After the nozzle was made by 3-D printing, the abrasive was sprayed on the surface of thecylindrical specimen and the cleaning performance test was performed. The effective cleaning area obtainedafter the analysis was similar to the size and shape of the effective cleaning area obtained after theexperiment. From this, the validity and effectiveness of the curved nozzle design was confirmed.
