Speed of Sound

Sound propagation velocity as a material property of single-phase fluids is a well-defined state function. For two-phase flows, however, the picture is completely different since the spatial distribution of the phases has an important influence on the propagation of sound. The present 'SoS Calculator' resorts to well-established theories to offer quick and simple estimates of the speed of sound in bubble, slug, and stratified flows. The input parameters of the calculator should be compatible with the simulated flow pattern. Once the conditions of your desired application are defined, run a multiphase flow simulator to find the dynamic properties of the flow. With this information in hand, access the simple and intuitive interface of the calculator to get your estimate. The SoS calculator is non-commercial software intended to be a practical tool for academic use. If you have any suggestions or would like to contribute to the improvement of the SoS Calculator, please contact us by email. Our suggested flow simulator is GALIA, which can be freely downloaded at https://www.nidf.ufrj.br/galia.
