Abstract: Abstract Self-sustained thermoacoustic oscillations as observed in low-emission combustion- involved gas turbines and aero-engines involve complicated thermal fluid–acoustics interaction and rich nonlinear dynamics. Such pulsating oscillations are known as thermoacoustic instability. When it occurs, large-amplitude… read more here.

Abstract: It is shown that the coexistence of synchronous and asynchronous states, being typical for chimera states in large networks of coupled oscillators, can be formed in a minimal chain of two coupled van der Pol… read more here.

DOI: 10.1515/ijnsns-2017-0024
Abstract: Abstract This paper presents the experimental investigation on synchronization of two Van der Pol oscillators with polynomial and delay unidirectional couplings. The intervals of coupling coefficients and delay leading to synchronization are determined experimentally using… read more here.
