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 singledroplet using Lagrangian-Eulerian numerical approach. Byusing Peng-Robinson equation and the van der Waalsmixing rule for the phase-equilibrium of n-heptane-nitrogensystem, the gas solubility at the droplet surface and the realgas behavior in the high pressures is considered. Theevaporation of one isolated n-heptane droplet is investigatedin the high pressure nitrogen environment and the resultsare compared with experiment data. The grid independencyis studied for better understanding of the fuel dropletgasification. The effect of the initial turbulent kinetic energyand turbulent dissipation rate is examined on theevaporation history of a fuel droplet too.
