- Abstract
- In this work, an assessment of different sub-grid scale (sgs) combustion models proposed for large eddy
simulation (LES) of steady turbulent premixed combustion (Colin et al., Phys. Fluids 12 (2000) 1843-1863;
Flohr and Pitsch, Proc. CTR Summer Program, 2000, pp. 61-82; Kim and Menon, Combust. Sci. Technol.
160 (2000) 119-150; Charlette et al., Combust. Flame 131 (2002) 159-180; Pitsch and Duchamp de Lageneste,
Proc. Combust. Inst. 29 (2002) 2001-2008) was performed to identify the model that best predicts
unsteadyflamepropagation in gas explosions. Numerical results were compared to the experimental data
by Patel et al. (Proc. Combust. Inst. 29 (2002) 1849-1854) for premixed deflagrating flame in a vented
chamber in the presence of three sequential obstacles. It is found that all sgs combustion models are able
to reproduce qualitatively the experiment in terms of step of flame acceleration and deceleration around
each obstacle, and shape of the propagating flame. Without adjusting any constants and parameters,
the sgs model by Charlette et al. also provides satisfactory quantitative predictions for flame speed and
pressure peak. Conversely, the sgs combustion models other than Charlette et al. give correct predictions
only after an ad hoc tuning of constants and parameters. (literal)
