Abstract:
A theoretical and experimental investigation was made of the combustion characteristics of nitrate ester droplets, including propylene glycol dinitrate, ethyl nitrate and n-propyl nitrate, at various ambient gas temperatures and pressures. Measurements were made of droplet diameter and temperature during combustion. At high pressures, the droplet ignited early in its heat-up period at a more or less fixed liquid temperature. At low pressures, the droplet ignited as its temperature approached the wet bulb temperature. A simplified theoretical model was found to give an adequate correlation of the ignition time in both regimes. A combustion model was formulated in studying the burning rates of the droplets. The model includes the effect of conviction on the burning rate. This model was found to be in fair agreement with the data.
