Séminaire PMMH - Dominic Vella (University of Oxford)
Drops with deformable boundaries : Flat tops, Locomotion and Ageing
A liquid droplet placed on a rigid, planar surface has a captivating simplicity : its surface is a spherical cap and remains in equilibrium. In this talk, I'll show that the addition of a deformable boundary leads to a range of new phenomena : evaporating droplets with an elastic skin may develop flat tops, while droplets placed in a flexible channel invariably push or pull themselves to the end of the channel. Even without a complex rheology or locomotion, reaching equilibrium can happen slowly, with the droplet's contact ageing. I will discuss three specific examples, presenting a combination of theory and experiment for each.

Vendredi 26 avril de 11h00 à 12h00 - Salle réunion PMMH 1
Interactions between submerged aquatic vegetation and flow : applications of ecohydraulics and biomechanics to ecological questions
Interactions between submerged aquatic vegetation and flow in rivers and streams are complex. Flowing water induces hydrodynamic stress on aquatic plants colonizing these habitats, which can, in some cases, cause mechanical failures such as breakage and uprooting. Additionally, aquatic plant beds have a (...) -

Getting smarter overnight : how automated experiments help unwind unsteady vortex-dominated flows
Abstract : Typical unsteady vortex-dominated flows like those involved in bio-inspired propulsion, unsteady airfoil separation, and vortex-induced vibrations can be prohibitively expensive to simulate and impossible to measure comprehensively. They are inherently non-linear, often involve moving boundaries, (...) -

Earthquake statistical properties : an explanation for the distribution of magnitude and for the existence of aftershocks
Earthquakes in nature follow several statistical properties. In particular, the distribution of energy released by an earthquake (Gutenberg-Richter's law) and the frequency of aftershocks after a large event (Omori's law) are both power-laws. By studying several earthquake models, we have shown that the (...) -

1D confinement controls cell shape and migration
Pericytes are mural cells of the microvasculature, they wrap around small vessels, support the vessels mechanically and participate in blood flow regulation. Pericytes are distinguished by two main characteristics ; first their distinct morphology, which has been likened to a “bump on a log”, as they present long (...)
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
