Hi all,

I have come across multiple papers which make reference to Fluent's "hard coded" augmented reduced mechanism, ARM19. I would like to use this mechanism within the composition PDF transport model, however after searching and searching, i cannot find out how to implement this mechanism with ANSYS 14.0.

I have found reference to files named "arm19.che" and "therm.dat", yet these files do not exist in my directories.

If it is hard coded, then no file importing would be necessary? Can someone please help with the process of utilising/enabling this mechanism?

Thanks

Check this paper

Good Luck

Thank you Vnm,

However the link produces a 404 Http error for me. Do you have a copy of the file or a name and author of the paper so i can attempt to retrieve it from the Uni Library?

Hi Clarkie_49,


I have the same problem; I've searched everywhere how I could implement a reduced mechanism in FLUENT but no way.
I'm confused because I don't find any arm9 file (should it already be in the FLUENT code?) , I don't know what to do with the CKWYP fortran subroutine.
Have you found something?

PS: the link you couldn't open should be : http://www.swri.org/utsr/presentatio...wLamnourPR.pdf but not really helping
There's also this one http://www.swri.org/utsr/summaries/FellowLamnourSUM.pdf

Hi friends,

Did you find an answer to this question. I need to use any of these reduced mechanisms too. I appreciate if you let me know if you find anything.

Hi there, you should provide the reduced mechanism, which is a plain text file containing the elements, species and reactions.

Something like this:

ELEMENTS
O H C N AR
END
SPECIES
H2 H O O2 OH H2O HO2
CH2 CH2(S) CH3 CH4 CO CO2 HCO
CH2O CH3O C2H4 C2H5 C2H6
N2 AR
END
REACTIONS
O+H+M<=>OH+M 5.000E+17 -1.000 0.00
H2/2.00/ H2O/6.00/ CH4/2.00/ CO/1.50/ CO2/2.00/ C2H6/3.00/ AR/0.70/
O+H2<=>H+OH 5.000E+04 2.670 6290.00
O+HO2<=>OH+O2 2.000E+13 0.000 0.00

ARM is included in Fluent. Try the steps outlined here

Cheers Man. But these links belong to 10 years ago and not accessible. I appreciate if you have share with everyone.
