Understanding the ultrasound field of high viscosity mixtures: Experimental and numerical investigation of a lab scale batch reactor

ABSTRACT: Highlights • Sonication of water-polyethylene glycol mixtures and study of viscosity increase on acoustic field.• Experimental investigation by calorimetry, sonochemiluminescence, aluminum foil erosion and particle image velocimetry.• Second sonication zone existence confirmation.• Viscosity threshold at ≈50 mPas for change in cavitation behavior.• Numerical investigation of the system for linear attenuation due to the presence of monodispersed cavitation bubbles. In this work, mixtures of increasing viscosity (from 0.9 to ≈720 mPas) are sonicated directly using an ultrasonic horn at 30 kHz to investigate the effect of viscosity on the ultrasound field both from an experimental and numerical point of view. The viscosity of the mixtures is modified by preparing water-polyethylene glycol sol
