Droplet Array Combustion Experiments on Effect of Initial Droplet Diameter on Flame Spread Characteristic Time

Fuel droplet array combustion experiments of a fuel droplet array were performed at microgravity to investigate the mechanism of fuel droplet group combustion. The purpose of this research is to understand the dependence of flame spread speed on droplet spacing and initial droplet diameter. Ten fuel droplets were generated using a thin glass needle and suspended at the crossing points with SiC fibers of 7.5 and 14 μm in diameter, respectively....
