- Summary, etc.
- The first microgravity combustion experiments were carried out in 2017 aboard the Japanese Experiment Module “Kibo“ on ISS, titled “Elucidation of Flame Spread and Group Combustion Excitation Mechanism of Randomly Distributed Droplet Clouds (Group Combustion).“ The flame spread over a large-scale droplet cloud consisting of about 100 droplets randomly distributed on a SiC-fiber lattice was observed. When droplets are generated one by one, the diameter of a droplet generated earlier changes more during large-scale droplet-cloud generation. The droplet pre-vaporization effect needed to be well understood to generate large-scale droplet clouds with a uniform initial droplet diameter for “Group Combustion“ experiments. We describe the concept of the large-scale droplet-cloud generation and report the vaporization-rate constants for a single droplet, for two interactive droplets and for a droplet cloud with n-decane as a fuel and verification results obtained in the “Group Combustion“ experiments aboard ISS. The evaluation of the vaporization-rate constant during the droplet-cloud generation suggests that the droplet vaporization in the droplet cloud occurred with interaction among many more than three droplets. Considering the pre-vaporization with the vaporization-rate constant estimated, most droplets had a nearly uniform diameter at ignition. Satisfactory reproducibility was confirmed in the droplet diameter at ignition and the flame-spread behavior.
