Modelling of automotive fuel droplet heating and evaporation: recent results and unsolved problems

Research output: Contribution to conferenceOther

Abstract

Recent results of the investigation of biodiesel, Diesel and gasoline fuel droplet heating and evaporation are summarised. The results of calculations of heating and evaporation of biodiesel fuel droplets, taking into account the contributions of all components, using the discrete components models with finite and infinitely large species diffusivities, and assuming that biodiesel fuel can be treated as a one component fuel, are discussed. It is pointed out that there are serious problems with the application of the discrete components model, based on the analysis of diffusion of individual components, to the modelling of heating and evaporation of realistic Diesel and gasoline fuel droplets. Some results of the development of the generalised multi-dimensional quasi-discrete model and its application to realistic Diesel and gasoline fuel droplets are presented. New approaches, based on kinetic and molecular dynamics models, are briefly summarised, and the most important unsolved problems are identified.
