Acoustically induced turbulence and shock waves are experimentally studies using hot-film anemometer and the following results obtained. (a) Shock waves and turbulence in a resonance tube can occur only when the sound pressure level passes a certain threshold value. The critical SPL for turbulence is approx. 158 dB which is slightly lower than SPL approx. = 160 dB for the shock wave formation. (b) Shock waves are found to be insensitive to frequency variations in contrast to standing waves where shock waves appear only within a narrow band around the resonance frequencies. (c) Isotropy of turbulence is checked by plotting spectrum against dimensionless frequency f/sub t/ of turbulence. In the inertial subrange, it is found that PSD ..cap alpha.. f/sub t//sup ..cap alpha../ with an average ..cap alpha.. = 1.85 which is only 10% from the theoretical value of -5/3 (4). (d) The rms turbulent velocity u/sub / has a functional dependence of I as u/sub / ..cap alpha.. I/sup 1/2/ regardless of locations but insensitive to variations of frequency. (e) The Reynolds number R in the form given by Merkli is found to be between 60 and 150 at the onset of acoustically induced turbulence. (f) The combined effect of turbulence and shock waves may have a vast influence on the agglomeration rate of aerosol particles. (g) A superimposed laminar flow onto the acoustically induced turbulence would suppress the turbulence under both traveling and standing wave conditions.
