The effect of ambient pressure on turbulent spray combustion behavior is investigated by means of Large-Eddy Simulation (LES). The ambient pressure is set to 0.1, 0.5 or 1.0 MPa. Jet-A is used as a liquid fuel. The evaporating droplets' motions are tracked by a Lagrangian method with non-equilibrium Langmuir-Knudsen evaporation model. As a turbulent combustion model, a flamelet/progress-variable approach which considers 274 chemical species and 1537 elementary reactions is used. The results show that as the ambient pressure increases, gas temperature increases and consequently droplet evaporation and soot production are enhanced in the upstream region.
