An Experimental Study on the Atomization Characteristics of a Two-Phase Turbulent Jet of Liquid Sheet Type Co-Axial Nozzle

액막형 동축노즐의 2상 난류분사의 미립화 특성에 관한 실험적 연구

In this study, a liquid sheet type co-axial nozzle has been used to investigate the turbulent atomization characteristics which could result in the experimental data to be used in designing a jet nozzle with high performance. Image processing technique and immersion sampling method were employed to measure droplet size. In atomizing characteristics, droplet size distributions and absolute droplet sizes, SMD(Sauter Mean Diameter) have been investigated in the wide ranges of flow field depending upon the air-water mass ratios. And the comparisons between the present data and the semi-empirical curves have been conducted semi-empirical correlation for SMD has been derived in the present analysis.
