7.8.3. Flamelet Libraries

A flamelet library provides the mean species mass fractions as functions of mean mixture fraction, variance of mixture fraction and scalar dissipation rate:

(7–38)

A separate Flamelet library is required for each fuel and each combination of fuel/oxidizer inlet temperatures and pressure level. The libraries shipped with CFX are listed in Table 7.1: Flamelet libraries included with CFX. The files reside in the subdirectory: <CFXROOT>/etc/reactions-extra/flamelet/

where <CFXROOT> is the location of your CFX installation.
