3J7b-3 Calorimetric Method for Measuring High Ultrasonic Powers Using Distilled Water as the Heating Material : Eliminating the Effects of Acoustic Streaming, Viscous Heating and Thermocouple Position(Medical ultrasound)

Abstract

In this study, we proposed a calorimetric method for measuring ultrasonic power that involves measuring the water temperature before and after ultrasonic irradiation. By using this method, problems associated with ultrasonic radiation including acoustic streaming, viscous heating and setting reproducibility can be removed. In the future, we intend to use this method to develop a standard for measuring the ultrasonic power.
