Abstract :
Active control has been shown as a feasible technology for suppressing thermoacoustic instability in continuous combustion systems, and the control strategy design is substantially dependent on the reliability of the flame model. In this paper, refinement of G-equation flame model for the dynamics of lean premixed combustion is investigated. Precisely, the dynamics between the flame speed Su and equivalence ratio φ are proposed based on numerical calculations and physical explanations. Finally, the developed model is tested on one set of experimental data.
