Hydrodynamic force on a small squirmer moving with a time-dependent velocity at small Reynolds numbers
T. Redaelli, F. Candelier, R. Mehaddi +2
We calculate the hydrodynamic force on a small spherical, unsteady squirmer moving with a time-dependent velocity in a fluid at rest, taking into account convective and unsteady fl…
Seismic response of cylinder assemblies in axial flow
Roberto Capanna, Guillaume Ricciardi, Emmanuelle Sarrouy +1
Earthquakes are a great challenge for the safety of nuclear reactors. To address this challenge, we need to better understand how the reactor core responds to seismic forcing. The…
Surfing on turbulence: a strategy for planktonic navigation
Rémi Monthiller, Aurore Loisy, Mimi A. R. Koehl +2
In marine plankton, many swimming species can perceive their environment with flow sensors. Can they use this flow information to travel faster in turbulence? To address this quest…
Zonal flow in a resonant precessing cylinder
Donglai Gao, Patrice Meunier, Stéphane Le Dizès +1
A cylinder undergoes precession when it rotates around its axis and this axis itself rotates around another direction. In a precessing cylinder full of fluid, a steady and axisymme…
The origin of hysteresis in the flag instability
Christophe Eloy, Nicolas Kofman, Lionel Schouveiler
The flapping flag instability occurs when a flexible cantilevered plate is immersed in a uniform airflow. To this day, the nonlinear aspects of this aeroelastic instability are lar…
Optimal Strouhal number for swimming animals
Christophe Eloy
To evaluate the swimming performances of aquatic animals, an important dimensionless quantity is the Strouhal number, St = fA/U, with f the tail-beat frequency, A the peak-to-peak…
Aeroelastic instability of cantilevered flexible plates in uniform flow
Christophe Eloy, Romain Lagrange, Claire Souilliez +1
We address the flutter instability of a flexible plate immersed in an axial flow. This instability is similar to flag flutter and results from the competition between destabilising…
