Abstract
In order to develop a simple method for preventing unwanted thermally driven acoustic gas oscillations, the amplitude-death phenomenon in thermoacoustic oscillators coupled by dissipative and time-delay coupling is experimentally studied. The coupling is designed and built using a needle valve and a half-wavelength tube. Experimental bifurcation diagrams show that oscillations can be completely stopped even in a system comprising identical oscillators when the oscillators are coupled by both dissipative and time-delay coupling. The effectiveness of this type of coupling is confirmed by numerical calculations.
