Experimental characterisation of the thermal behaviour of different materials submitted to ultrasound in an ultrasonic fountain.

The purpose of this study was to characterize the thermal behaviour of different materials subjected to an ultrasonic fountain created by an ultrasonic piezoelectric transducer. Tests were conducted with an infrared camera to determine the surface temperature of the material samples. The main conclusion is that the plastics when subjected to the ultrasonic fountain tend to heat up strongly and can reach temperatures up to 200 °C in few seconds.
