Hydrogen combustion mechanism

engineer2020 · September 20, 2019, 04:09

Hello everybody

Does anybody have the Hydrogen combustion mechanism including 9 species and 19 steps?

Actuallu I could not find such a file on the Internet.

Your help would be highly appreciated.

Just e-mail Michael Burke.

Which mechanisms are you looking for if it's not Burke's?

Actually this very mechanism consists of 9 species and 19 steps.

I just found it at an article.

The picture of that mechanism is attached.

Is there any Chemkin file for this mechanism?

Which model is this? What article?

AFAIK, the most recent model for H2/O2 is:
Burke, M. P., Chaos, M., Ju, Y., Dryer, F. L., and Klippenstein, S. J. "Comprehensive H2/O2 kinetic model for high-pressure combustion," International Journal of Chemical Kinetics Vol. 44, No. 7, 2012, pp. 444-474. doi: 10.1002/kin.20603

Hello

Actually I saw this article (Comprehensive H2/O2 Kinetic Model for High-Pressure Combustio) but the problem is that my reference has 9 species including O2,H,H2,OH,O,H2O,N2,H2O2 and HO2 and 19 steps. Your recommended mechanism has 11 species (Ar and He are not on my reference's mechanism).

So should I enter the species and steps by myself into Fluent?

This is my reference by which I am going to validate my results:
Dmitry Pashchenko, "Comparative analysis of hydrogen/air combustion CFD-modeling for 3D and 2D computational domain of micro-cylindrical combustor", international journal of hydrogen energy, 2017.

Your help would be highly appreciated

I mean you can, it's straightforward. It just takes awhile (maybe 1 hour of your time). It's usually better (for us lazy folks) to just ask the author for their input files.

Hi
Does anyone have the Jachimowski reaction mechanism ( 9 species 19 steps) for hydrogen air combustion?

Hi Imran,

Have you found this mechanism file?

It's written on his paper in 1988.
