Název v původním jazyce

Interaction between two nonlinear acoustic resonators

Popis výsledku v původním jazyce

This work is dedicated to problems connected with an interaction between two nonlinear acoustic cylindrical resonators. The resonators are closed and interact due to an elastically mounted wall which is placed between them. This wall represents a one-degree-of-freedom mechanical oscillator that is described by the linear equation of motion. Acoustic fields inside the resonators are generated by vibrating pistons which are located at their ends. The pistons are capable to excite nonlinear standing waves.For description of the waves model equations were derived, which represent the modified inhomogeneous Burgers equations. Nonlinear acoustic fields are coupled linearly by the elastically mounted wall. This resonant system enables to set a lot of configurations which is due to many optional parameters, e.g. frequency and amplitude of the vibrating pistons, detuning, characteristic frequency of the mechanical oscillator and its damping. This paper contains interesting analysis of chosen c
