- Abstract
- An experimental method to study combustion of free fuel droplets at reduced gravity has been developed. Reduced gravity environment was achieved by performing the experiments in a drop tower. The experimental technique was based on the parabolic projectile motion of a fuel droplet. A test fuel droplet was propelled almost vertically upward from a droplet generator in a combustion chamber. As soom as the droplet reached the apex of its trajectory, the droplet was ignited, and simultaneously the camera which was positioned at the apex of the droplet trajectory and which was used to obtain photographic record of the burning droplet, the combustion chamber, and the associated instrumentation were release into free fall. In this way the burning droplet would experience reduced gravity, and at the same time the droplet was leviated (i.e., unsupported) with respect to the free falling package. Detailed designs of the experimental hardware used to perform the experiments will be discussed. Experimental observations of burning of unsupported fuel droplets by using the present technique will be presented.
