Gases and bubbles in molten glasses: from chemical engineering to geosciences
Atelier 2016
Various industrial processes involve multiphase flows. In such systems the dynamics is the result of interactions between phases.
In particular, bubbles in liquid undergo various phenomena such as, among others, nucleation, growth or shrinkage, coalescence or break-up. This physics occurs in a furnace of glass melting but also in a glass of Champagne.
Volatile species as noble gases and halogens or the system C-O-H-S are often dissolved in natural media like magma. The exsolution of these species are crucial to investigate the volcano eruption. The physics involved here is the same nature that for industrial chemical reactors.
During this workshop, we want to gather researchers working in various fields like chemical engineering, fluid mechanics, materials sciences, geophysics to draw the state of art on gases and bubbles in glasses and melts to address problems like nucleation, diffusion and sollubility of gases, chemical reactions
or multiphase flows.
