Ultrasonic measurements of spherical resonator characteristics and determination their errors

Abstract

Spherical resonator is usually used for excitation of physical phenomena known as single-bubble cavitation and single-bubble sonoluminiscence. It is evident that a creation of the cavitation bubble demands very specific conditions. A cell for these experiments has to have certain characteristics. Moreover characteristics of used liquid like speed of sound, density and kinematic viscosity should be known for precise description of the bubble dynamics. Described measurement method that follows is focused to determination of characteristics of used spherical resonator.
