The evolution of turbulence theories and the need for continuous wavelets
Marie Farge
In the first part of this article, I summarise two centuries of research on turbulence. I also critically discuss some of the interpretations that are still in use, as turbulence r…
The impact of turbulence on flying insects in tethered and free flight: high-resolution numerical experiments
Thomas Engels, Dmitry Kolomenskiy, Kai Schneider +3
Flapping insects are remarkably agile fliers, adapted to a highly turbulent environment. We present a series of high resolution numerical simulations of a bumblebee interacting wit…
Helical vortices generated by flapping wings of bumblebees
T. Engels, D. Kolomenskiy, K. Schneider +3
High resolution direct numerical simulations of rotating and flapping bumblebee wings are presented and their aerodynamics is studied focusing on the role of leading edge vortices…
Wavelet-based regularization of the Galerkin truncated three-dimensional incompressible Euler flows
Marie Farge, Naoya Okamoto, Kai Schneider +1
We present numerical simulations of the three-dimensional Galerkin truncated incompressible Euler equations that we integrate in time while regularizing the solution by applying a…
Energy dissipation caused by boundary layer instability at vanishing viscosity
Romain Nguyen van yen, Mathias Waidmann, Rupert Klein +2
A qualitative explanation for the scaling of energy dissipation by high Reynolds number fluid flows in contact with solid obstacles is proposed in the light of recent mathematical…
Coherent structure extraction in turbulent channel flow using boundary adapted wavelets
Teluo Sakurai, Katsunori Yoshimatsu, Kai Schneider +3
We present a construction of isotropic boundary adapted wavelets, which are orthogonal and yield a multi-resolution analysis. We analyze direct numerical simulation data of turbule…
