| Popis: | Results investigating the processes—of generation and collection of monodisperse droplets flowing in microgravity and high vacuum—are presented. We applied these results to droplet radiators for systems of thermal stabilization and low-potential heat rejection from spacecraft power systems. The experiments were conducted on the “Mir” orbital station. Main constituents of the working process were reproduced: Generation of the droplets and collection of droplets flow on the moving fluid film at the collector surface. The developed model—with systems of measurement, thermal stabilization, and control—allowed us to obtain and record information about the process in the model in real time and (by telemetry, video recording, etc.). As a result of this space experiment, and for the first time in microgravitation and high vacuum, we demonstrated the feasibility to realize forced capillary breakdown of jets into monodisperse droplets, under the action of acoustic oscillations. A stable ancillary film of working fl... |
