In the tutorial oppositeBurningPanels, in the chemistryProperties dictionary, the sub-dictionary reactions reads:

reactions
(
irreversibleSolidArrheniusReaction
v = gas + char
(7.83e10 15274.57 300 4.86)
);

The number 4.86 is the reaction order.

Does anyone have any clue on how this number was obtained?

Thanks,

Paulo

Hi Paulo,
To my little understanding this is taken from the database.

Hi Naveed,

Thanks for the reply.

To what database you refer to?
I searched my OpenFOAM installation and didn't find anything that refers to 4.86 in a solid reaction.

Regards,

Paulo

Hi Paulo,
I do not mean the data base in OpenFOAM. There are certain databases existing in external to OF world. The researchers have documented thousands of reactions, with the reaction order, activation energy and other related parameter. I do not have any name in my mind, but you can easily find them. I was referring to that database.
