液滴散热器（LDR）在排热功率重量比方面优于传统散热器。因此，LDR作为高功率空间系统的先进辐射器，将成为大型空间结构的先决条件。本研究从未来LDR空间应用的角度出发，探讨微重力条件下液滴发射器的性能。通过实验，认为在微重力条件下，在无量纲波数为0.215 ~ 0.490的范围内，液滴发射器可以产生均匀的液滴流。在此范围内，液滴直径为204 ~ 285 μm，间距为445 ~ 1160 μm。并得出结论，这些直径和间距可以估计的方程的基础上的质量守恒定律的生成过程中的液滴。
The Liquid Droplet Radiator (LDR) has an advantage over comparable conventional radiators in terms of the rejected heat power-weight ratio. Therefore, the LDR has attracted as an advanced radiator for high-power space systems that will be prerequisite for large space structures. In this study, the performance of a droplet emittor under microgravity condition has been investigated from the viewpoint of operational space use of the LDR in the future. From experiments, it is considered that the droplet emittor can produce uniform droplet streams under microgravity condition in the non-dimensional wave number range from 0.215 to 0.490. In this range, the droplet diameter and the spacing range are from 204 to 285 [μm] and from 445 to 1 160 [μm] respectively. And it is concluded that these diameter and spacing can be estimated by the equations based on the law of conservation of mass in the process of generating droplets.
