Interaction between flame-spread and droplet motion has been investigated to have basic understandings of the spray combustion mechanism. New experimental apparatus was developed to measure interactive force acting on n-heptane droplets during droplet pair combustion. A droplet array suspension system consists of two SiC fiber of 8.5 micrometers in diameter and a silver bead. Droplet motion was recorded with a high-speed video camera. The force was calculated from the droplet position history. Initial droplet diameter was set at 1.0 mm. Two droplets were ignited simultaneously by a hot wire. The force acting on the droplet more than 0.1 μN can be measured.
