Experimental study of nonane/hexanol mixture droplet combustion without natural or forced convection

In this paper we present new data on the combustion of stationary nonane/hexanol mixture droplets burning in microgravity to promote spherical symmetry. Compositions of 10%, 25%, 40%, 60%, and 80% (volume percent hexanol) were examined in a drop tower to create an environment whereby droplets could burn without a strong influence of buoyancy. The evolution of droplet, soot shell, and flame diameter were measured, and photographs are presented to...
