Four-winged flapping flyer in forward flight
Ramiro Godoy-Diana, Prasann Jain, Mariana Centeno +2
We study experimentally a four-winged flapping flyer with chord-wise flexible wings in a self-propelled setup. For a given physical configuration of the flyer (i.e. fixed distance…
Large-amplitude undulatory swimming near a wall
Rafael Fernández-Prats, Veronica Raspa, Benjamin Thiria +2
The propulsive dynamics of a flexible undulating foil in a self-propelled swimming configuration near a wall is studied experimentally. Measurements of the swimming speed and the p…
Conditional averaging on volumetric velocity fields for analysis of the pseudo-periodic organization of jet-in-crossflow vortices
Tristan Cambonie
Volumetric velocimetry measurements have been performed on a round jet in crossflow (JICF). Two kind of conditional averaging process are presented : a global conditional average (…
Two-phase flow in a chemically active porous medium
Alexandre Darmon, Michael Benzaquen, Thomas Salez +1
We study the problem of the transformation of a given reactant species into an immiscible product species, as they flow through a chemically active porous medium. We derive the equ…
Seeding optimization for instantaneous volumetric velocimetry. Application to a jet in crossflow
Tristan Cambonie, Jean-Luc Aider
Every volumetric velocimetry measurements based on tracer (particles, bubbles, etc.) detection can be strongly influenced by the optical screening phenomenon. It has to be taken in…
Transition scenario of the round jet in crossflow topology at low velocity ratios
Tristan Cambonie, Jean-Luc Aider
We study experimentally a round Jet In CrossFlow (JICF) at low values of the jet to-crossflow velocity ratio R using instantaneous and time-averaged three-dimensions three-componen…
