단일유체노즐의 미분무 분사 조건이 열복사 감쇠에 미치는 영향에 대한 실험적 연구

Abstract

In this study, the effect of water mist spray condition on thermal radiation attenuation was experimentally investigated. Two types of single-fluid nozzles were used to generate the water mist. To investigate the characteristics of water mist, the water supply pressure was reported, and the droplet size and droplet velocity of water mist sprayed from one and two nozzles were measured with the visualization of water mist. Then, the effects of nozzle installation location and water mist sprayed from two nozzles on the thermal radiation attenuation (i.e., measured heat flux, attenuated heat flux, and attenuation rate) were measured. Based on the measurement data of water mist characteristics, the general trends of thermal radiation attenuation were analyzed in detail.
