Characterization of the performance of a minibubble generator in conditions relevant to microgravity

We perform a characterization of a recently reported minibubbles (bubbles with a diameter of the order of 10‐3 m) generator in microgravity related conditions. Generation of bubbles is based on the generation of a slug flow in a capillary T‐junction, whose operation is robust to changes in the gravi...
