Augmented reduced mechanism for methane by J.-Y. Chen

Hagen · September 11, 2014, 12:53

Dear Foamer's,

I am working on methane/air combustion. As the full mechanism that describes the chemistry kinetics is very expensive, I use reduced mechansims. So far I was happy with the 4-steps/7-species mechanism by Jones-Lindstedt or 16 species mechanism by Smooke.

However, especially at higher pressures the Augmented Reduced Mechanism (ARM) of J.-Y. Chen (COMBUSTION AND FLAME 125:906 –919 (2001)) is probably better. The only problem, the implementation in OpenFOAM is, I believe, not straightforward since steady state reactions are involved. A Frortran routine is available here: http://www.sandia.gov/TNF/chemistry.html

My question is, has anybody tried to use this mechanism in OpenFOAM? How could this be done?

Thank you!
Hagen

Dear Hagen,

Could you please share the files of the reduced mechanism of 4-steps/7-species mechanism by Jones-Lindstedt or 16 species mechanism by Smooke. I need them badly. Thanks.

Tom

hello Tomladian,

you can search online for "Simplified Kinetic schemes for oxy-fuel combustion" by A frassoldati, which contains jones-lindstedt mechanism in chemkin format in table2. Also the JL method is mentioned in the book "High Temperature Combustion-chapter3 by Hiroshi Tsuji".
