Abstract

This article extends the results of the experiments at the earth gravity described in Part I to the case of the parabolic flight experiments conducted in Bordeaux, France, in June 2013 on a Novespace plane during a parabolic flight campaign that was supported by NASA and ESA. This second part details the droplet generator, heating system and the experimental rig developed for the flight experiments at zero gravity (0g) and supergravity (1.8g). Even though the setup used in the flights was an offshoot of the setup developed in the ground experiments of Part I, it had a number of modifications dictated by safety and space restrictions. After the experimental Section 1, the results of the heat flux measurements during the parabolic flights are described and discussed in Section 2, followed by conclusions.
