Abstract
Experimental techniques using cold and hot wire anemometry have been developed to measure acoustic temperature and velocity oscillations in gases, respectively, especially in the case where there is no imposed mean flow. The calibration of both instruments was made through the measurement of the pressure oscillation. Using these techniques the structures of thermal and viscous oscillatory boundary layers produced by an acoustic standing wave in air with 130-Hz frequency and pressure oscillation amplitude up to 200 Pa are determined. Experimental results are satisfactorily compared to theoretical results of a linear theory. The advantages and the limitations of these experimental techniques are discussed.
