Reaction mechanism for LPG fuel (60/40 butane/propane)

pradeep6890 · August 19, 2020, 02:21

Hello there,
I am currently simulating Liquefied Petroleum gas based lean burn spark ignition engine where I need help in selecting the proper mechanism for LPg combustion.
The fuel i use contains 60% butane and 40% propane. How/where do i get mechanism file for this?

Thank you in advance

it is a very easy question. you can search the keywords "butane" and "skeletal mechanism" in the sciencedict. you can download several butane skeletal mechanisms of butane in other researches' paper. In the oxidation process of butane, the propane is a very important middle species. you can select one that contains both butane and propane skeletal mechanism.

thank you. But If it was tat easy i wouldnt have posted here. I easily get butane and propane mechanism separately but I asked for LPG combined of both. hope you understood. thank you.

There is a link for more information about this UCSD mech (58 species and 270 reactions).

There is another link for more information about this NUI Gallway mech (293 species and 1593 reactions).
