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 ...

Thermoacoustic Soret separation
The Journal of the Acoustical Society of America, 2022 In a fluid mixture in a channel with an axial time-averaged temperature gradient, high-amplitude oscillating flow can greatly increase the axial flux of thermal diffusion (Soret) separation of the components of the mixture. The enhancement occurs when the oscillating lateral temperature gradient greatly exceeds the axial gradient, causing a large ...

Sampling in thermoacoustic tomography [PDF]
Journal of Inverse and Ill-posed Problems, 2020 AbstractWe explore the effect of sampling rates when measuring data given byMffor special operatorsMarising in Thermoacoustic Tomography. We start with sampling requirements onMfgivenfsatisfying certain conditions. After this we discuss the resolution limit onfposed by the sampling rate ofMfwithout assuming any conditions on these sampling rates.
