Application of Transfer Function Analysis to Combustion Oscillations using Well-Stirred Reactor Modelling,
Abstract
Combustion in many cases is accompanied by noise, which may be due to natural turbulence of the combustion gases, or to feedback. In this project effort was concentrated on the last type of noise, i.e., feedback oscillations. These oscillations belong to a class of self-excited oscillations in which a normally steady supply of energy (the flame) is modulated through a passive feedback loop (the combustion chamber and the burner). The main object of this project was to define transfer functions for the oscillating combustion system, knowledge of which may enable one to prevent oscillations at the design stage. The major variables involved in these transfer functions have been identified and the validity of the mathematical model proposed is demonstrated. (Modified author abstract)
