Abstract

A novel ultrasonic reactor was designed based on the optimization of acoustic dynamics of its geometry. The reactor relies on 3 frequencies of operation to achieve greater cavitation coverage and greater sonochemical efficiency through more intense bubble collapse. The cavitating region of the vessel is evaluated using a passive acoustic emission hydrophone as well as aluminium foil erosion tests. Results indicate agreement between aluminium foil erosion and broadband acoustic emission from the hydrophone. Erosion results provide validation for multiple frequency reactor design approach in terms of maximizing the cavitating region.
