Flamelet Table Generator

Solve steady counterflow diffusion flamelets with Cantera across a strain-rate sweep, trace the S-curve with extinguished points flagged, and tabulate presumed β-PDF flamelet/progress-variable lookup tables for turbulent combustion models.
Estimated minimum cost: $—

Examples

Mechanism

The kinetic mechanism for every flamelet: a bundled Cantera data file, a Cantera YAML (for example a reduced mechanism), or a single-file Chemkin mechanism with its thermodynamic data inline. Transport data is required. Up to 300 species.

Fuel and oxidizer streams

The two opposed jets. Compositions are mole fractions written as SPECIES:amount (normalized by Cantera), for example CH4:1 against O2:0.21, N2:0.79.

Strain-rate sweep

Strain rates to solve, from near-equilibrium through extinction. Each one adds a flamelet to the library and a point to the S-curve.

20 of 40 strain points.

Mixture fraction, progress variable and tables

How flamelets are parameterized and which quantities the tables carry. Leave the progress variable blank to use the CO2, H2O, CO and H2 products of the mechanism (weight 1); leave the species blank for the progress-variable species, the stream species and OH.

Up to 11,781 table rows.

Solver settings

Grid refinement for each flamelet. Leave blank for the defaults; tighter slope and curve add grid points and solve time. Transport is mixture-averaged.
