Our Principal Research Physicist, Andrew Hurrell, has co-written a paper ‘Characterization of shock waves in power ultrasound‘ with colleagues from Oxford Brookes, Greenwich and Brunel Universities. This paper presents the measurements of the shock waves emitted by cavitating bubbles in water, under ultrasonic excitation produced by an immersed probe oscillating at 24 kHz.
This work contributes towards the elucidation of the key properties of cavitation-driven shock waves and the underlying mechanisms, essential in controlling the effectiveness of the external processing conditions on various physical, chemical and biological systems. The published paper can be found online at the Journal of Fluid Mechanics from Cambridge University Press.
