摘　　要：液滴式辐射器中液滴的喷射性能决定了液滴层中液滴的直径、间距、速度等参数,进而决定了整个液滴层的辐射散热性能。利用Rayleigh-Weber射流理论初步确定产生均匀液滴流的频率范围,完成了喷射实验装置的设计。通过实验研究了工质压力、扰动频率、喷孔的直径、喷孔长径比对均匀液滴流产生的影响。Diameter,space,velocity and other parameters of droplets,and then the heat radiation performance of the whole droplet layer,are determined by the droplet injection performance of liquid droplet radiator.Utilizing the Rayleigh-Weber jet theory,the frequency range at which uniform liquid droplet flow are output was preliminarily figured out,and the design of this experimental injection device.Through tests,the effects of working medium pressure,disturbance frequency,jet orifice diameter and length-diameter ratio on uniform droplet flow were verified.
