Investigation of an isolated n-heptane droplet evaporation in high pressure nitrogen environment using Eulerian-Lagrangian approach

This paper reports on the evaporation history of a single droplet using Lagrangian-Eulerian numerical approach. By using Peng-Robinson equation and the van der Waals mixing rule for the phase-equilibrium of n-heptane-nitrogen system, the gas solubility at the droplet surface and the real gas behavior in the high pressures is considered. The evaporation of one isolated n-heptane droplet is investigated in the high pressure nitrogen environment and the results are compared with experiment data. The grid independency is studied for better understanding of the fuel droplet gasification. The effect of the initial turbulent kinetic energy and turbulent dissipation rate is examined on the evaporation history of a fuel droplet too.
