Abstract
Abstract–The disruptive combustion of probe-supported and free-falling Al/C/JP-lO slurry droplets (200 to 1OOO, μm in diameter) was investigated experimentally. The disruption processes and disruption times were analyzed using backlit or natural-light film records taken with a high-speed motion picture camera. Parametric studies were conducted to investigate the influence of the relative proportions of aluminum and carbon in the solids and of surfactant and stabilizing additive levels; and disruption times were quantified with respect to droplet diameter, total solids loading. ambient gas temperature, and oxygen mole fraction. Slurry composition parameters were found to affect the type and strength of the observed disruptive phenomena presumably by altering the porosity and plasticity of the surface shells of solids formed during the early stages of gasification.
