Abstract
Global shipping uses Heavy Fuel Oil (HFO) as the primary fuel. HFO is a mixture of oil refinery residue and cutter stock,
hence it contains large numbers of hydrocarbons with a wide range of molecular weights and dissimilar structures.
Conventional thermodynamics modelling techniques are inadequate for HFO vaporisation modelling. The present article
summarises continuous thermodynamics vaporization models along with chemical kinetics models for decomposition and
polymerisation, and soot burnout models, employed to study the behaviour of HFO spray combustion. A sample of HFO
is also characterised in the laboratory using chemical characterisation procedures including sequential elution solvent
chromatography, gas-chromatography mass spectrometry and elemental analysis, to obtain the composition and mean
molecular weights of HFO fractions required for continuous thermodynamics modelling. Models are implemented via
subroutines in a diesel spray simulation in the CFD package STAR-CD. The simulation is applied to a constant volume
spray combustion chamber. The present model accounts for the formation and burnout of liquid phase soot in diesel
engines. This soot will be emitted as Black Carbon if unburnt. The models are examined for two representative fuel
samples; one with the good combustion quality and the other with poor. Good qualitative agreement is shown between the
simulations and published experimental data.
