Acoustic and hydrodynamic turbulence-turbulence interaction and its influence on acoustic particulate agglomeration

The potential application of acoustic agglomeration of aerosols in industry are usually under high flow rate conditions. The acoustic hydrodynamic turbulence-turbulence interaction in a resonance tube is studied. Measurements are made at both loop and node positions with a sound pressure level of 161.5 dB (re 20 (SIBMA)Pa) and the hydrodynamic Reynolds number Re ranging from 0 to 14,000. Important parameters of the final state such as the rms turbulent velocity, the integral scale, the Taylor and Kolmogorov microscales and the rate of turbulent energy dissipation epsilon are estimated. It is found that as long as the hydrodynamic flow is turbulent epsilon increases monotonically with increasing values of Re.
