Release notes:

JetSurF 1.0-l features

· a detailed reaction model (USC-Mech II) for small hydrocarbon pyrolysis and oxidation,

· a lumped model of 9-species for n-C_xH_2x+2 (12 ≥ x ≥ 5, less undecane) cracking to form C₁-C₄ fragments.

This represents a considerable simplification over the detailed chemistry of n-alkanes in JetSurF v.1.0 (83 species and 675 reactions). Combined with USC-Mech II, the total simplified model features 120 species and 977 reactions describing the pyrolysis and oxidation kinetics of all normal alkanes up to n-dodecane at high temperatures. It is possible to reduce the detailed USC-Mech II to obtain a fully reduced model for CFD applications.

The method with which we obtained the lumped model and a selected set of validation tests
are documented in

“JetSurF 1.0-l¹ is a simplified version of JetSurF 1.0.² It features a lumped model for n-alkane
cracking and a detailed USC Mech II³ for the pyrolysis and oxidation of C₁-C₄ hydrocxarbons.”

Note:

Detailed reaction model development is inherently a work in progress. The current release is for the purpose of discussion and evaluation. Although JetSurF1.0 and its reduced models are capable of predicting a large body of experimental data, it should be used with caution. The current release is meant to be used for modeling the pyrolysis and oxidation of n-alkane (up to n-dodecane) at high temperatures only.
