Effects of natural convection on high-pressure droplet combustion

Burning behavior of a suspended fuel droplet under both normal and microgravity fields has been studied experimentally to explore the effects of natural convection at high ambient pressure levels up to four times the fuel critical pressure. The fuel employed was n-octane. Experiments have shown that the burning rate constant increases with the increase of the ambient pressure at subcritical pressures and decreases at supercritical pressures for...
