Abstract
  • The micro-explosion phenomenon consists in the explosive vaporization of water droplets inside a droplet of water-in-oil emulsion. It is used in the combustion of emulsified fuels. The distribution of temperature and thermal energy of the \"daughter-droplets\" issued from a micro-explosion remains unknown so far. The difficulty of such an investigation is their small size and fast velocity, for an on-the-fly characterization. The present investigation explains an experimental facility designed to record the temperature field on a thermally thin plate, when impacted by the droplets issued from a micro-explosion. The distribution of maximum temperatures at impact is shown, on a representative sample of droplets. A complete calculation is exposed, that enables to obtain the thermal energy of droplets from the unsteady temperature field on the plate. (literal)
