Abstract
Thermoacoustic instability is a phenomenom that appears in several technical applications, for instance rocket and jet engines, gas turbines, waste generators and industrial burners where it can cause heavy damage to the systems. As with most instabilities, they are undesired and this thesis' purpose is to identify and control a Rijke tube process (which has been used to stimulate the thermoacoustic instabilities) with the aid of microphones and a loudspeaker. A major part of the work has been done on setting up such a process, considering for instance the necessary high sample rates and make future experiments possible and also to show that the process can be controlled with very simple means in a very simple environment.
