| Outline of Final Research Achievements |
One of the candidates to solve the waste heat problem of large space systems such as space solar power systems is a liquid droplet radiator. The data of the effective emissivity of the radiating surface formed by the droplet stream is essential in order to design the liquid droplet radiator. In this study, a technique for obtaining the effective emissivity by a radiative heat transfer experiment and numerical analysis using Monte Carlo method has been established. It is clarified from this approach that the effective emissivities of three kinds of a single droplet flow (droplet diameter: 0.118, 0.106, 0.090 mm, droplet spacing: 0.630, 0.435, 0.212 mm) are 0.073, 0.087, and 0.12, respectively.
