The research activities "interfacial instabilities and atomisation" address issues concerning liquid fragmentation (of a jet or a sheet)such as size or velocity of inclusions. We aim at understanding and model the main mechanism that govern such fragmentation. A large part of our efforts concern assisted atomization: a liquid jet is broken into droplets by a fast parallel gaz jet. This process is involved in numerous applications related to motors (turbojet, rocket engine,...). The other activities are also related to industrial issues (droplet ejection by wheels, ergol storage, hydroelectric facilities,...)

Lack of knowledge regarding air entrainment caused by large jets in hydraulic (...)
We study the entrainment of water in air by a rotating wheel that is partially immersed on a fraction of its radius. The goal is the prediction of the nature of the spray of droplets around a car (...)
