Researchers have developed a measuring device to maximise the efficiency of cavitation processes used in manufacturing. Berenice Baker reports
A sensor that measures localised sonic cavitation could be used to monitor and improve the quality of numerous production processes, according to its developers at the National Physical Laboratory.
Ultrasonic cavitation is used to produce consistent crystalline pharmaceuticals and chemicals, clean printed circuit boards, aerospace and automotive components and sterilise medical equipment. It occurs when sound waves are passed through a fluid to oscillate bubbles of dissolved gas, causing them to implode and so ...
