Development of a Detailed Chemical Kinetic Model for 1-Methylnaphthalene.

1-Methylnaphthalene is a critical component for constructing fuel surrogates of diesel and aviation kerosene. However, the reaction pathways of 1-methylnaphthalene included in existing detailed chemical kinetic models vary from each other, leading to discrepancies in the simulation of ignition and oxidation processes. In the present study, reaction classes and pathways involved in the combustion of 1-methylnaphthalene were analyzed, and effects of rate constants of reactions related to 1-methylnaphthalene and its significant intermediates on ignition delay times and species concentration profiles were discussed, involving hydrogen abstraction and substitution reactions of 1-methylnaphthalene, oxidation, isomerization, and addition reactions of 1-naphthylmethyl, hydrogen abstraction and oxidation reactions of indene, as well as the oxidation of indenyl and naphthalene.

Design, optimization and application of reformer in a marine natural gas engine: A numerical and experimental study.

In the present study, the models of flow, heat transfer and reforming of 2-D single reforming tube and 3-D reformer core inside the reformer were implemented by CFD. The models were evaluated by comparison of simulations with data derived from a catalytic packed-bed reactor. In addition, a NG engine-reformer experimental system was established.
