Thermoacoustic Instability
Continuous combustion processes are prominently encountered in many applications related to power generation, heating and propulsion. Examples include domestic and industrial burners, steam and gas turbines, waste generators, and jet and ramjet engines. Continuous combustion processes exhibit a wide range of dynamics. Of these, conditions which promote coupling with the acoustic field and resul...
متن کاملA Model-Based Active Control Design for Thermoacoustic Instability
Active control has been pursued vigorously for combating thermoacoustic instabilities in combustion processes. Most experimental investigations employ empirical design procedure for determining the characteristic parameters of the filter and phase-shifter of the controller. Such procedure has been observed to result in resonance at frequencies which were not excited in the power spectrum of the...
متن کاملA Model-Based Self-Tuning Controller for Thermoacoustic Instability
Active control of thermoacoustic instabilities in continuous premixed combustion processes is being increasingly investigated for operating at lean low NOX conditions. Recently, we have developed a model-based approach for active control design which accounts for the underlying acoustics, heat release dynamics, and sensor and actuator dynamics. While this model captures a number of the dominant...
متن کاملIntermittency Route to Strange Nonchaotic Attractors
Strange nonchaotic attractors (SNA) arise in quasiperiodically driven systems in the neighborhood of a saddle node bifurcation whereby a strange attractor is replaced by a periodic (torus) attractor. This transition is accompanied by Type-I intermittency. The largest nontrivial Lyapunov exponent Λ is a good order–parameter for this route from chaos to SNA to periodic motion: the signature is di...
متن کاملThermoacoustic instability: model-based optimal control designs and experimental validation
Active control of thermoacoustic instability has been increasingly sought after in the past two decades to suppress pressure oscillations while maintaining other performance objectives such as low NOx emission, high efficiency and power density. Recently, we have developed a feedback model of a premixed laminar combustor which captures several dominant features in the combustion process such as...
