PLOGArrheniusReactions

A library for OpenFOAM to handel the PLOG keywords in reactions.

Support has been added from OpenFOAM-7 to the latest OpenFOAM-13.

Support has been added to some ESI versions. We have tested OpenFOAM-v2112 and OpenFOAM-v2506, and a test case is provided. A user might expect this code to function normally for all ESI versions between v2112 and v2506.

This has been reported but has not yet been solved.

For more information, please refer to the defination of PLOG, and also the Troe keyword in the OpenFOAM source code.

In Chemkin, PLOG is shown as

C3H4+H=CH3CCH2 9.2E+38 -8.65 7000. !(This is a dummy reaction rate for Chemkin) 
 PLOG /0.1 9.2E+38 -8.65 7000./ 
 PLOG /1. 9.5E+42 -9.43 11200./ 
 PLOG /10. 1.5E+45 -9.69 15100./ 
 PLOG /100. 1.8E+43 -8.78 16800./ 
 PLOG /1.0E+5 4.4E+09 1.45 2400./ 

which is written as

  type            reversibleArrheniusPLOG;
  reaction        "C3H4+H=CH3CCH2";
  A               9.2E+35;//convert mol to kmol
  beta            -8.65;
  Ta              3522.73274;//convert Ea to Ta, Ta = Ea/R (8.314 J⋅K−1⋅mol−1), cal to J (4.18400 J/cal)
