Recent Progress in the Implementation of Active Combustion Control

Abstract

Active combustion control has received increasing attention for the suppression of pressure oscillations and the extension of flammability limits in dump combustors and premixed combustors with flameholders. In order to accelerate progress in this emerging area, a research program was initiated to improve the physical understanding of combustion dynamics, develop new actuators, and explore new control strategies. This paper describes progress made in the program. The role of shear-flow dynamics in combustion control through experiments and numerical large-eddy simulation has been clarified. New actuators to manipulate the shear layer and increase acoustic level by utilizing periodic chemical energy release have been demonstrated. New control strategies based on neural network, adaptive filter, and modern control synthesis procedures have been implemented
