Abstract:
In this dissertation, based on the method of recurrence plot and its application in dynamic system analysis we examine the behavior and dynamic analysis of a swirl burner. Though retrospective studies on thermoacoustic instability have been performed on single-blown premixed cone shape flames and several combustion systems but so far this method has not been considered for a real combustion system. There have also been more work on phenomena known as the flame separation from the burner (blowout) and its propagation into the burner (flashback), which is almost conscious of their process. In fact, selecting a single flame has been to eliminate the flame-flame interactions in the system.
The combustion system that we will work on in this thesis is a swirl burner. Experimental data will be obtained from this burner and then, using the recurrence plotting method, we will identify the flame dynamical system. This can provide a platform for testing the types of burners and combustion systems to solve their problems by identifying the dynamics that govern them
