8.5.2 Multiple Steady Flamelet Libraries

ANSYS FLUENT can generate multiple steady flamelets over a range of strain rates to account for the varying strain field in your multi-dimensional simulation. If you specify the number of flamelets to be greater than one, flamelets are generated at scalar dissipation values as determined by Equation  8.5-1.

where $i$ ranges from 1 up to the specified maximum number of flamelets, $\chi_0$ is the initial scalar dissipation, and $\Delta \chi$ is the scalar dissipation step. Flamelets are generated until either the maximum number of flamelets is reached, or the flamelet extinguishes. Extinguished flamelets are excluded from the flamelet library.
