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 ...
