Abstract
For the purpose of exploring the fundamental phenomenon of spray turbulent combustion, this research aims to investigate interactions between droplet flames and vortex tubes composing coherent structure of turbulence using a model based on a droplet flame in varying forced convection. A fuel droplet is placed at the focusing point of the swinging forced convection apparatus installed in a high-pressure combustion chamber. An analogy between the interaction and the model was discussed in order to determine the experimental condition. Experimental apparatus for microgravity experiment was developed and tested using MGLAB dropshaft, finding a response of instantaneous burning rate constant to the varying flow.
