An Experimental study on the drop size and velocity characteristic of drop by impinging jets
충돌분류에 의한 액적의 크기 및 속도특성에 관한 실험적 연구
Abstract
The breakup characteristics of liquid sheet formed by the liquid rocket injector has a close relation with the combustion efficiency. In this paper, basic characteristics of droplet size and velocity distribution were measured with PDPA for the Like Doublet Impinging Injector. Test variables were the angle of impact, the diameter of orifice and jet velocity. Water was used as test fluid. As a result, for impingement angle less than 90 degree, following correlations were obtained between drop size and design parameters :
