OpenFOAM simulation using DME

Yujuan · July 29, 2019, 12:43

Hello FOAMers,

I'm doing combustion simulation using OpenFOAM. The fuel is DME, and the mechanism is Zhao's mechanism(Zhao Z, Chaos M, Kazakov A, Dryer FL. Thermal decomposition reaction and a comprehensive kinetic model of dimethyl ether. Int J Chem Kinet 2008;40:1–18. doi:10.1002/kin.20285.).

The problem is that when I use the original mechanism and thermo file downloading from the website, there are always errors related to chemistryReader. Then I deleted some redundant numerical flags in last column of the thermo file, as well as some blanks in mechanism file. Then the errors disappear. However, the new problem is that the program always crashes at the first step(errors are attached below), specifically, combustion->correct(). I also tested the mechanism with the reactingFoam, there are still errors. When I substitute the mechanism file with others (like gri30), there is no problem. So I am just wondering whether the mechanism and thermo files are not read correctly. Can anyone who have succeeded in DME simulation using OpenFOAM share these two files with me? Thanks a lot.

Does the mechanism contain any fall-off type reaction in TROE form with some coefficients (Ts, Tsss) as zero?

Have you tried running tests in chemFoam with this mechanism?

Thanks a lot for your reply. Yes, I found that the problem is due to the following reaction:
! Wang et al., JPC A 107:11414 (2003)
CH3+CH3(+M) = C2H6(+M) 2.277E+15 -0.69 1.7486E+02
LOW/8.054E+31 -3.75 9.816E+02/
TROE/0.0 570.0 0.0 1.E+30/
H2O/5/ CO/2/ CO2/3/
Since Ts is set to be zero, the program just gets an error of floating pointing exception.
I wonder if I should change the value of Ts to a very small value, like 1E-31? Or I should use substitutes for this reaction?

Sounds reasonable to me.
