Towards In-service Acoustic Characterization of Gaseous Microbubbles Applied to Liquid Sodium

Résumé

The characterization of argon microbubbles in liquid nitrogen is currently being investigated in connection with the development of Generation IV nuclear reactors. It seems that non-linear acoustic techniques can be used to determine the void fraction (volumetric fraction of free gas) and the histogram of the bubble radiuses. We discuss the first stage of our work here: the installation of an experimental test bench suitable for generating air microbubbles in water and then measuring them optically, before attempting an acoustic characterization. The bubble clouds generated have a radius distribution centred on about 20 microns.
