The dataset consists of four kinetics mechanisms for four different fuel blends. The fuels are Jet A1, Jet A1/DMC, Jet A1/EtOH and Jet A1/PODE. These mechanisms can be used in engine simulations when the fuels stated are present in the engine. Softwares that can be used with the mechanisms are kinetics and CHEMKIN Pro. The mechanisms can be used without modifications. The zipped folder contains four sub-folders with chemical mechanisms of Jet A1, dimethyl carbonate (DMC), ethanol (EtOH) and polyoxymethylene dimethyl ether (PODE). Within each of the sub-folders, there are two txt files with the chemical mechanism file and thermo file in CHEMKIN format. The details of the simulation conditions can be found in the manuscript.
