Flamelet tab of the
Species Model panel (Figure
15.11.1), you will enter values for parameters of the flamelet(s).

Flamelet Parameters are as follows:
Number of Grid Points in Flamelet
specifies the number of mixture fraction grid points distributed between the oxidizer (
) and the fuel (
). Increased resolution will provide greater accuracy, but since the flamelet species and temperature are solved coupled and implicit in
space, the solution time and memory requirements increase greatly with the number of
Maximum Number of Flamelets
specifies the maximum number of laminar flamelet profiles to be calculated. If the flamelet extinguishes before this number is reached, flamelet generation is halted and the actual number of flamelets in the flamelet library will be less than this value.
Initial Scalar Dissipation
is the scalar dissipation of the first flamelet in the library. This corresponds to
Scalar Dissipation Step
specifies the interval between scalar dissipation values (in s
) for which multiple flamelets will be calculated. This corresponds to
Calculate Flamelets to begin the laminar flamelet calculation. Sample output for a flamelet calculation is shown below.
