  We have designed and constructed an experimental system to study gas bubble
growth in slightly supersatu- rated liquids. This is achieved by working with
carbon dioxide dissolved in water, pressurized at a maximum of 1 MPa and
applying a small pressure drop from saturation conditions. Bubbles grow from
hydrophobic cavities etched on silicon wafers, which allows us to control their
number and position. Hence, the experiment can be used to investigate the
interaction among bubbles growing in close proximity when the main mass
transfer mechanism is diffusion and there is a limited availability of the
dissolved species.
