The measurement of thermoacoustic phenomena using thermoacoustic couples [PDF]
The Journal of the Acoustical Society of America, 1989 The results of measurements of thermoacoustically generated temperature gradients in thermoacoustic couples (TACs) subjected to acoustic standing waves are reported. The value of the temperature gradient is a function of the acoustic pressure amplitude, mean gas pressure, type of gas, TAC construction, and its position in the standing wave ...

On the influence of external stochastic excitation on linear oscillators with subcritical self-excitation applied to brake squeal [PDF]
, 2019 A characteristic of linear systems with self-excitation is the occurrence of non-normal modes. Because of this non-normality, there may be a significant growth in the vibration amplitude at the beginning of the transient process even in the case of ...
