Springer Effect of Noise on a Model Thermoacoustic System at its Stability Boundary by Richard Steinert
In experiments on a_x000D_prototypical combustor, Richard Steinert identifies new insights on the impact_x000D_of noise on the phenomenon known as thermoacoustic instability. The phenomenon_x000D_is a concerning issue which creates a technical limit on the efficiency and_x000D_environmental impact of fossil fuels combustion in industrial combustors. It_x000D_poses a threat to the structural integrity of practical systems such as gas_x000D_turbine combustors and rocket engines. The experiments demonstrate that_x000D_thermoacoustic systems feature an interesting noise-induced behaviour known as_x000D_coherence resonance - a coherent response of dynamical systems close to their_x000D_stability boundary that is induced by stochastic excitation. The work contained_x000D_in this publication is an example illustrating the importance of fundamental_x000D_considerations in solving perplexing engineering issues._x000D_ Table of contents :- _x000D_
