FLUPS -- a flexible and performant massively parallel Fourier transform library
Pierre Balty, Philippe Chatelain, Thomas Gillis
Massively parallel Fourier transforms are widely used in computational sciences, and specifically in computational fluid dynamics which involves unbounded Poisson problems. In prac…
An immersed interface method for the 2D vorticity-velocity Navier-Stokes equations with multiple bodies
James Gabbard, Thomas Gillis, Philippe Chatelain +1
We present an immersed interface method for the vorticity-velocity form of the 2D Navier Stokes equations that directly addresses challenges posed by multiply connected domains, no…
String stability of energy-saving aircraft formations
James R. Riehl, Esteban A. L. Hufstedler, Philippe Chatelain +1
Groups of aircraft have the potential to save significant amounts of energy by flying in formations; all but the leading aircraft can benefit from the upwash of the wakes of preced…
Stability and sensitivity analysis of bird flapping flight
Gianmarco Ducci, Victor Colognesi, Gennaro Vitucci +2
This paper investigates stability analysis of flapping flight. Due to time-varying aerodynamic forces, such systems do not display fixed points of equilibrium. The problem is there…
FLUPS: a Fourier-based Library of Unbounded Poisson Solvers
Denis-Gabriel Caprace, Thomas Gillis, Philippe Chatelain
A Fourier-based Library of Unbounded Poisson Solvers (FLUPS) for 2D and 3D homogeneous distributed grids is presented. It is designed to handle every possible combination of period…
Simulations of propelling and energy harvesting articulated bodies via vortex particle-mesh methods
Caroline Bernier, Mattia Gazzola, Renaud Ronsse +1
The emergence and understanding of new design paradigms that exploit flow induced mechanical instabilities for propulsion or energy harvesting demands robust and accurate flow stru…
