TWO-DIMENSIONAL FLAME INSTABILITY AND CONTROL OF BURNING IN THE HAlF-OPEN FIRECHAMBER

Abstract

The flame stability with regard to two-dimensional exponential perturbations both for the combustion in the half-open fire-chamber and the flame propagating in half-open channels is investigated. It is proved that only instability ispossible for the combustion process. At the same time the one-dimensional flame instability is guaranteed near the front wall of the fire-chamber where the fuel supply is realized. Possibilities for the control of combustion in the halfopenfire-chamber and diminishing of intensity of pulsations are discussed.
