Stick-slip-to-stick transition of liquid oscillations in a U-shaped tube
François Gallaire, Alessandro Bongarzone
The nonlinear decay of oscillations of a liquid column in a U-shaped tube is investigated within the theoretical framework of the projection method formalized by Bongarzone et al. [Chaos 31, 123124 (2021)]. Starting from the full hydrodynamic system supple ...
Amer Physical Soc2024Wetting Dynamics Beneath an Impacting Droplet
Many natural and industrial processes involve fluid flow at a three phase interface between liquid, solid and gas. When the liquid is forced to move rapidly over the solid surface, the physical mechanisms governing contact line motions are multi-phase and ...
EPFL2023Stay close, but not too close: aerial image analysis reveals patterns of social distancing in seal colonies
Devis Tuia, Benjamin Alexander Kellenberger
Many species aggregate in dense colonies. Species-specific spatial patterns provide clues about how colonies are shaped by various (a)biotic factors, including predation, temperature regulation or disease transmission. Using aerial imagery, we examined the ...
2023Spatially explicit effective reproduction numbers from incidence and mobility data
Andrea Rinaldo, Cristiano Trevisin, Enrico Bertuzzo, Lorenzo Mari, Damiano Pasetto, Marino Gatto
Current methods for near real-time estimation of effective reproduction numbers from surveillance data overlook mobility fluxes of infectors and susceptible individuals within a spatially connected network (the metapopulation). Exchanges of infections amon ...
2023Spectroscopy and dynamics at liquid water interfaces
This thesis is a detailed description of three experimental investigations on aqueous interfaces. All projects made use of the microjet technology or the more recently developed flat-jet technique which enables the implementation of liquid water in vacuum ...
EPFL2022Dynamic wetting in pressure-infiltration of ceramic particle preforms by molten metal
This thesis investigates the interaction between mechanically induced flow of a liquid metal into a porous solid, and kinetic effects at the triple line. The approach is experimental and focuses on metal-ceramic systems for which the literature gives value ...
EPFL2019Surfing the capillary wave: Wetting dynamics beneath an impacting drop
John Martin Kolinski, Ramin Kaviani
The initiation of contact between liquid and a dry solid is of great fundamental and practical importance. We experimentally probe the dynamics of wetting that occur when an impacting drop first contacts a dry surface. We show that, initially, wetting is m ...
AMER PHYSICAL SOC2019Virus transfer at the skin-liquid interface and its associated risks
Infectious diseases are a leading cause of death across the world. One of the primary causes of infectious diseases are viruses. Since liquids are highly important in the transmission of viruses, the aims of this work are to i) quantify the transfer of vir ...
EPFL2018Virus transfer at the skin-liquid interface
Understanding virus transfer between liquid and skin is necessary to estimate transmission during water-related activities. In the present study, we modeled virus transfer from liquid-to-skin and skin-to-liquid. Specifically, we performed human subject stu ...
Amer Chemical Soc2017Studies on fluid dynamics of the flow field and gas transfer in orbitally shaken tubes
Florian Maria Wurm, David Hacker, Xiao Shen, Dominique Terry Monteil Jr, Likuan Zhu
Orbitally shaken cylindrical bioreactors [OrbShake bioreactors (OSRs)] without an impeller or sparger are increasingly being used for the suspension cultivation of mammalian cells. Among small volume OSRs, 50-mL tubes with a ventilated cap (OSR50), origina ...
