About

This mechanism has been derived by Quentin Malé at CERFACS for iso-octane combustion.

It is derived using YARC from a skeletal mechanism called SPK produced at ICARE laboratory .

It comprises 21 transported species, 11 QSS species and 201 reactions.

Only Cantera version of this mechanism exists.

compa_thick: Laminar flame thickness of an iso-octane/air from 1D premixed Cantera flames. Initial temperature evolves with pressure respecting an isentropic compression with gamma=1.4.

compa_Tadia: Laminar flame final temperatures of an iso-octane/air from 1D premixed Cantera flames. Initial temperature evolves with pressure respecting an isentropic compression with gamma=1.4.

compa_AI: Auto-ignition delay time of an iso-octane/air, based on the maximum of wOH, from 0D homogeneous reactors at constant pressure 1, 5 and 10 bar.

compa_mixNburn: Inflammation delays tl based on the maximum of wOH after mixing with burnt gases (composition from combustion at constant pressure of an iso-octane/air mix at Pinit=1 bar, Tinit=300 K and phi=1.0) and fresh gases (same operating conditions).
