EFFECT OF THE REYNOLDS AND LEWIS NUMBER TO THE FUEL DROPLET VAPORIZATION

ABSTRACT
In this work we present the effect of Reynolds and Lewis numbers on the fuel droplet vaporization of n-heptane. This study allows us to fully understand the vaporization phenomenon of fine fuel droplets (spray) in energy systems in order to improve combustion efficiency, reduce the formation of pollutants and unburned materials such as CO and NOx. The study is based on an analytical solution of the governing equations of the vaporization process by calculating the droplet diameter evolution, the temperature at the surface of the droplet, the mass fraction of fuel vapor and the mass-flow rate. The analytical results obtained by the theoretical model are compared to the experimental data in order to validate our results.
