... 614 Modeling of Combustion Systems: A Practical Approach
Usually, one defines a reaction coordinate known as the conversion (x
k
),
having the property that for species k the reaction starts at ... is a constant
and N
k
is a variable. We may also write
(G.6)
For constant density, we have
,
where [k] is the concentration of species k, and [k

that both the forward and reverse reactions occur (typically at different rates),
k is an index from 1 to n products, p

Consider a general reaction:
