Abstract
The effect of ambient pressure on droplets' evaporation is investigated by means of threedimensional Direct Numerical Simulation (DNS). The results show that as the ambient pressure increases, the droplet lifetime increases at low initial gas temperature of 1000 K, and decreases at high initial gas temperature of 1500 K, respectively, for both cases with and without combustion. In addition, the decrease of droplet lifetime at high initial gas temperature of 1500 K becomes more remarkable for the cases with combustion.
