Abstract
The sound emitted by a bubble of gas dissolved in a fluid medium is a phenomenon that has been studied since the late nineteenth century. In order to identify the frequency spectrum of this type of acoustic emission, different mathematical models have been proposed since then. In the present article, preliminary results of the computational simulation of the classic Minnaert and Strassberg models are presented. After the adequate validation of these models against experimental measurements of acoustic emission of air leaks generated in the test tank of the EPUSP Dynamics and Instrumentation Laboratory, these models will be used to generate a priori estimates of the acoustic properties of signals characteristic of gas leaks.
