Abstract
In a standing wave thermoacoustic resonator, a strong interaction between the oscillating fluid and the solid boundaries in the stack induces a transfer of acoustic power manifesting itself by heat flux on the stack control surfaces. Measurement of the structure of the thermal boundary layer is of interest and practical importance because of the poor understanding of the nature of the hydrodynamic energy transfer along the plates. This work for the first time addressed an experimental study of the time-resolved temperature oscillation of the oscillating flow in a parallel-plate stack with an imposed temperature gradient, by using constant current anemometry techniques. This, combined with the velocity measurements using particle image velocimetry reveals the phase relation between the temperature and velocity oscillations at selected test conditions.
