Abstract

This study, carried out by NPL in collaboration with the Institute of Sound & Vibration Research, comprised a literature review, questionnaire survey, and feasibility experiments. The experiments explored the use of ‘standard’ water samples, specifically “water purified”, and “AnalaR water”, and also purified water loaded with hydrophobic polystyrene spheres, contained within a reference ultrasonic cleaning vessel, as a reproducible cavitating medium. A novel piezoelectric cavitation sensor was used to assess the cavitation activity.
Results indicated best prospects for reproducible behaviour using the ‘standard’ water samples. Further work is needed to quantify this reproducibility, by testing other water sample batches and using water containing different levels of trace particulates.
This study was carried out under the UK National Measurement System Programme for
Acoustical Metrology, 1999-2001.
