PMMH at a glance




CONCOURS EXTERNE 2015

Ingénieur d’Etude - CNRS



The PMMH laboratory includes between 70 and 80 people, including about forty permanent members who work essentially at the CNRS, ESPCI, University Paris VI and University Paris VII.

The research activities of PMMH are hydrodynamics, soft matter, chemical and physical biology, solid mechanics and statistical physics.



Featured story

La nature pour modèle

Conçu au PMMH, ce micronageur artificiel, d’un diamètre d’un millimètre, reproduit les mouvements de l’anguille. Il est ici filmé (de gauche à droite) alors qu’il avance à une dizaine de centimètres par seconde. En haut et en noir, sa tête oscille sous (...)


Self-replicating cracks : a collaborative fracture mode in thin films

Des physiciens du PMMH viennent de mettre en évidence un nouveau mode de rupture d’un film mince déposé sur une surface. Lorsque cette couche craquèle tout en se décollant, les fissures forment des motifs particulièrement réguliers tels que spirales, (...)

PRE Editors’ Suggestion - Prediction of frequencies in thermosolutal convection from mean flows

S. E. Turton, L. S. Tuckerman and D. Barkley Phys. Rev. E 91, 043009 – Published 14 April 2015. Motivated by studies of the cylinder wake, in which the vortex-shedding frequency can be obtained from the mean flow, we study thermosolutal (...)


PRE Editor’s suggestion - Edge effects on water droplet condensation

Marie-Gabrielle Medici, Anne Mongruel, Laurent Royon, and Daniel Beysens, Phys. Rev. E 90, 062403 (2014). In this study we investigate the effect of geometrical or thermal discontinuities on the growth of water droplets condensing on a cooled (...)

The force of impacting rain



D. Soto, A. Borel De Larivière, X. Boutillon, C. Clanet and D. Quéré, Soft Matter, 2014, 10, 4929.

Drop impacts are difficult to characterize due to their transient, non-stationary nature. We discuss the force generated during such impacts, a ...

Microrheology to probe non-local effects in dense granular flows


M. Bouzid, M. Trulsson, P. Claudin, E. Clément and B. Andreotti, EPL, 109 (2015) 24002.


A granular material is observed to flow under the Coulomb yield criterion as soon
as this criterion is satisfied in a remote but contiguous region of space....
