PLOGArrheniusReactions

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