Experimental Investigation on the Flow Characteristics of High Pressurized Jet with Nozzle Aspect Ratio
노즐 형상비에 따른 고압분사의 유동 특성에 관한 실험적 연구

Abstract
High-pressurized jet is widely using in industrial works. however, few papers studied on the performances or characteristics on that kind of nozzles. And in this study, some flow characteristics with the variation of nozzle aspect ratios such as mean velocity distributions, momentum variations along the center line have been experimentally investigated. As the results, some semi-empirical correlations of profiles of pressure and mean velocity distributions, momentum conservations with the nozzle aspect ratios are formulated. It is expected that these empirical formula can be applied for the random estimations of nozzle performances.
