A prospective method to assess thermo-acoustic instabilities based on two reflection coefficients measured from the upstream side of the burner is presented and experimentally validated. In order to compose a model which allows predicting the onset o

The interplays between acoustic and intrinsic modes in a model of a Rijke burner are revealed and their influence on the prediction of thermoacoustic instabilities is demonstrated. To this end, the system is examined for a range of time delays, tempe

Heat exchangers are an essential constituent part of many combustion systems. The thermoacoustic instability in such systems is a common problem and it has been studied extensively. However, the heat exchanger has not gained much attention in the fie

Bounds are derived for the acoustic losses such that a thermoacoustic system with a given flame can be guaranteed to be stable. The analysis is based on the flame’s acoustic input-to-output properties represented by its scattering matrix. The devel

Similarly to chemi-luminescence, a chemi-ionization mechanism is imbedded in the chain of carbon oxidation (heat release) for hydrocarbons–air flames which involves fast reactions between radicals. This fact suggests to use this chemi-ionization ra

One promising approach to eliminate thermoacoustic instabilities in combustion appliances is the use of adaptive control of the flame/burner acoustic transfer function (TF). Application of a DC electric field (EF) as a spatially distributed, easily a

The thermoacoustic stability behaviour of a flame is experimentally investigated in the presence of large acoustic losses. Recently it has become clear that under such conditions an instability can occur due to an intrinsic local feedbackloop at the

Experimental and numerical techniques to characterize the response of premixed methane-air flames to acoustic waves are discussed and applied to a multi-slit Bunsen burner. The steady flame shape, flame front kinematics and flow field of acoustically

The thermo-acoustic behaviour of multiple premixed laminar flames is analysed. The idea is used to (de)compose the flame Transfer Function (TF) of composite multiple flame configurations to/from the TF of constituent sub-systems of the flame. The TF
