Enhanced Evaporation of Droplet of Ternary Component Under the Effect of Thermo-physical and Transport Properties Variability

摘要

This work simulates the heat and mass transfer of the fuel droplets evaporated in a hot medium. The proposed model includes the vaporization of multi-component fuel droplet, in laminar forced convection. The results show that the various components, of different molecular weights, vaporize at different temperatures. Furthermore, the non-miscibility of the mixture of the hydrocarbons liquid droplet is observed. The profile of the regression of the droplet square diameter does not follow the law and presents three evaporation rates rather than a single one. New correlations for the evaporation rate versus Reynolds and Schmidt numbers are proposed for different air velocities, different initial droplet radii, and different initial mass fractions.
