357CFD Modeling of Oxygen-Enhanced Combustion
3. Instead of just precalculating, the amelet
library can be recalculated iteratively after each
ow calculations. The ow calculations have
then to be reconverged using updated ame-
let library. The two-way coupling between the
amelet library and the CFD calculations makes
the simulations computationally expensive and
rigorous. The amelet library loses its general-
ity since it is generated for specic situations.
14.5.4.4.3 Steady Laminar Flamelet Model
For Da ≫ 1 the chemistry becomes fast enough for the
ame to respond instantaneously to aerodynamic strain.
The transient terms in the amelet equations can then
be neglected leading to the so-called steady laminar
amelet model. The transience ...
