- •
The Lewis fugacity rule gives good results at low temperatures and moderate pressures.
- •
A water diffusivity model is introduced for the evaporation of emulsion droplets.
- •
The chemistry tables used for the combustion model are small and compact.
- •
The combustion model is more sensitive to changes in enthalpy than in fuel fraction.
