Could someone explain how to write the recombination tables for a specific mixture in CMutationTCLib.cpp in SU2. I would like to use a carbon mixture and their mechanisms which we have compiled in the Mutation library but couldn't figure out how to write the recombination tables.

Can someone take the example of the Air-5 mixture and explain what each element in the matrix refers to and how the values of the constants decided.

It would be really helpful if someone can explain it soon, Thanks in Advance .

Hello Cherith.


My colleague Jacob implemented this, I'll ask him to reply here.

Hi Cherith,
Are you referring specifically to the catalytic wall recombination?

If so, the tables are formulated as follows:

CatRecombTable(Species#,0) = +1, -1, or 0
This determines if the species is created, destroyed or nothing happens. For these models the recombination assumes all monoatomic species (N and O) would recombine into N2 or O2.

So CatRecombTable(3,0) = 1 essentially is saying the 4th species is created...which in Mutation++ notation is N2.


CatRecombTable(#Species,1) determines the species corresponding to its creation or destruction.

So in the example above:
CatRecombTable(3,0) = 0 is basically saying the N2 species that is created depends on the recombination of species #0..which is N.

I hope this helps,
Wally

Thank You So Much for the clarification.

Also I wanted to ask if Implicit Time Integration is available yet for the Simulations using Mutation++??

Sincerely
Cherith

Implicit time integration is not available with Mutation++
