摘要:
A Droplet Burning Facility which allows the investigation of droplet vaporization and burning under various dynamic and thermal conditions has been constructed. The system has been operated during the parabolic flights of the NASA KC135 aircraft. An important set of data has been collected on the low temperature turbulent vaporization and envelope burning of suspended n‐heptane droplets at ground and reduced gravity conditions. From digitized images obtained by a rapid video camera, the time evolution of the droplet and the flame dimensions are determined with great accuracy. The information is used to deduce the vaporization rate constant, the flame diameter and the flame standoff ratio under various conditions.
