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…
Adaptive solution of initial value problems by a dynamical Galerkin scheme
Rodrigo M. Pereira, Natacha Nguyen van yen, Kai Schneider +1
We study dynamical Galerkin schemes for evolutionary partial differential equations (PDEs), where the projection operator changes over time. When selecting a subset of basis functi…
A wavelet-adaptive method for multiscale simulation of turbulent flows in flying insects
Thomas Engels, Kai Schneider, Julius Reiss +1
We present a wavelet-based adaptive method for computing 3D multiscale flows in complex, time-dependent geometries, implemented on massively parallel computers. While our focus is…
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…
