Abstract

Biography

The importance of modelling the multi-component fuel droplets heating and evaporation has been recognised in many studies within this field. Studies on the heating and evaporation of automotive fuel droplets are crucial to the design of internal combustion engines and to ensuring their good performance. Accurate modelling is essential to the understanding of these processes and ultimately to the improvement of engine design and reducing emission. The interest in fossil/biodiesel fuel blends has been mainly stimulated by depletion of fossil fuels and the need to reduce carbon dioxide emissions that contribute towards climate change.
This work presents a review of recent investigations into the heating and evaporation of multi-component blended fuel droplets in real IC engine conditions. The models consider the contribution of all groups of hydrocarbons in fossil fuels and methyl esters in biodiesel fuels. Diffusion of these components, temperature gradient, and recirculation within droplets are accounted for. The original modelling approach is based on the analytical solutions to the heat transfer and species diffusion equations, which is validated against experimental data.
The key features of new application to the analysis of blended-fuel droplets in engine-like conditions is described. In this review, up to 20 types of biodiesel fuels with up to 21 methyl esters and 98 components of hydrocarbons are considered, accounting for the differences in their levels of saturation, and thermodynamic and transport properties.
