Abstract

The aluminum droplet's burning detail is important for propellant capability. Based on Fick's first law and Fourier law, the mass and energy diffusion process between gases produced by burning aluminum droplet was computed. Following the track of the intermediate product, the development of droplet's size, component, and combustion efficiency were studied. Results show that in early process, the reaction is more intense. After 60 ms, the burning becomes placid. Finally, about 20% of the droplet surface is covered by the oxide cap.

Key words： solid rocket propellant; aluminum droplet; transient combustion; oxide cap
