A small-scale (7.6m) drop water tower was used for studying the combustion of unsupported fuel droplets (about 500..mu..m initial diameter) in a stagnant ambience under very low gravity. The droplets were observed over the period of burning from ignition to burnout. 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 freefall when the droplet reached the apex. A review of some results are presented for droplets consisting of single component liquids (toluene and heptane) and a binary miscible mixture of heptane and hexadecane. The evolution of droplet diameter is reported and comparisons with prior experiments are made. 17 refs., 5 figs.
