摘要:
A small‐scale (7.6m) drop tower was used for studying the combustion of unsupported fuel droplets (about 500 &mgr;m initial diameter) in a stagnant ambience under lower gravity. The experimental procedure consisted of generating a droplet in a near vertical trajectory and then releasing the chamber within which the droplet was introduced, as well as associated instrumentation, into free‐fall when the droplet reached the apex of its trajectory.Some results of the burning of n‐heptane, toluene, and heptane/hexadecane mixture droplets are reported. The range of the heptane data is discussed in terms of possibly varying ambient conditions around the droplet during burning due to droplet motion. Microexplosions were not observed for the mixture reported.
