Viscous growth and rebound of a bubble near a rigid surface
Sebastien Michelin, Giacomo Gallino, Francois Gallaire +1
Motivated by the dynamics of microbubbles near catalytic surfaces in bubble-powered microrockets, we consider theoretically the growth of a free spherical bubble near a flat no-sli…

Edge states control droplet break-up in sub-critical extensional flows
Giacomo Gallino, Tobias M. Schneider, François Gallaire
A fluid droplet suspended in an extensional flow of moderate intensity may break into pieces, depending on the amplitude of the initial droplet deformation. In subcritical uniaxial…

Physics of Bubble-Propelled Microrockets
Giacomo Gallino, Francois Gallaire, Eric Lauga +1
A popular method to induce synthetic propulsion at the microscale is to use the forces created by surface-produced gas bubbles inside the asymmetric body of a catalytic swimmer (re…
