Buckling instability causes inertial thrust for spherical swimmers at all scales
A. Djellouli, P. Marmottant, H. Djeridi +2
Microswimmers, and among them aspirant microrobots, generally have to cope with flows where viscous forces are dominant, characterized by a low Reynolds number (). This implies…
Fast acoustic tweezers for the two-dimensional manipulation of individual particles in microfluidic channels
S. B. Q. Tran, Philippe Marmottant, Pierre Thibault
This paper presents a microfluidic device that implements standing surface acoustic waves in order to handle single cells, droplets, and generally particles. The particles are move…
Acoustically bound crystals
P. Marmottant, D. Rabaud, P. Thibault +1
In these fluid dynamics videos, we show how bubbles flowing in a thin microchannel interact under an acoustic field. Because of acoustic interactions without direct contact, bubble…
A periodic microfluidic bubbling oscillator: insight into the stability of two-phase microflows
Jan-Paul Raven, Philippe Marmottant
This letter describes a periodically oscillating microfoam flow. For constant input parameters, both the produced bubble volume and the flow rate vary over a factor two. We explici…
Dry microfoams: Formation and flow in a confined channel
Jan-Paul Raven, Philippe Marmottant, François Graner
We present an experimental investigation of the agglomeration of microbubbles into a 2D microfoam and its flow in a rectangular microchannel. Using a flow-focusing method, we produ…
