Effect of acoustic radiation pressure on air bubbles

Abstract

In this paper, we will shed light on the impact of  ultrasound waves on air bubbles formed within the media, including so-called radiated pressure, where the voice of the tsunami working to make air bubbles in a certain way when exposed to it. This behavior depends on the radius of bubbles.  These phenomena have been studied theoretically. Laws and theories under which aerobic bubbles were concluded since the fifties of the last century by scientists Kawashima, Yosioka and Hirano. In the beginning of the century, this subject received attention of many scientists in different countries in order to confirm the theories that have been reached and approved them by experiments. One of those experiments will be presented in this research concerned with behavior of air bubbles when exposed to radiation from ultrasound waves. Small bubbles which have a radius smaller than the radius resonant gathered in groups toward the trough of sound waves and large bubbles in the opposite direction where this behavior studied in case of ongoing and suspended waves.
