Atomization Characteristics of Gelled Fuels Containing Different Concentrations of Metal Particles

Gelled fuels have promising applications in the aerospace field. Higher density and calorific value can be achieved with addition of energetic metal particles to gelled fuels, which also effectively improve combustion efficiency fuel thus enhance engine performance. However, make rheological properties more complex, introduces difficulties regarding their atomization combustion. In order investigate effect concentration on characteristics was prepared three particle concentrations 0%, 15%, 30%. this paper, were tested by a rotational rheometer, (spray cone angle, Sauter mean diameter (SMD), droplet size distribution) measured experimentally. nozzle structures designed, including DC nozzle, swirl self-excited oscillation nozzle. The effects different are compared discussed.
