Modelling of droplet heating and evaporation

Basic principles of the Discrete Component (DC) model and its application to biodiesel fuel droplets are summarised. Main ideas of the Multi-dimensional Quasi-discrete (MDQD) model and its applications to Diesel and gasoline fuel droplets are discussed. The influence of droplet non-sphericity on their heating and evaporation, approximating droplet shapes as prolate and oblate spheroids, is described. The temperature gradients inside and at the surface of the droplets, and the changes in their shape during the heating and evaporation process are taken into account. Some new developments in gas phase heating and evaporation models for mono- and multi-component fuel droplets are presented. A self-consistent kinetic model for droplet heating and evaporation is briefly described. New approaches to the estimation of the evaporation coefficient, including those taking into account quantum-chemical effects, are summarised.
