•A wide range of models are
available to simulation combustion reactions
•Eddy Dissipation Model
–suitable for fast reactions
•Finite Rate Chemistry Model
–suitable for slower reactions
•Single and multi-step
reactions
•Laminar Flamelet Model
–suitable for diffusion flames (reaction
occurs only at the flame surface)
•NOx and Soot models
•Extended Coherent Flame
Model
–Used for
premixed or partially premixed combustion, where fuel and oxidizer do not
immediately burn when mixed
–Includes wall
quenching capability, where reaction stops when mixture touches a wall
Recommended for
Internal Combustion Engine studies
•Residual Material Model
–Unburned
reactants from one combustion cycle can be burned in future cycles
–Can be used to
model Exhaust Gas Recirculation
•Auto-Ignition
–When fuel and
air is at sufficiently high temperature, ignition occurs
–Used for
modelling compression-ignition engines (diesel engines)
–Can be used to
predict premature ignition (“knock”) in spark-ignition engines
