Wake interactions drive synchronized vortex merging in a hovering quadcopter
Elias S. Pratschke, Claus C. Wolf, Daniel Schanz +2
The most energetic coherent structure of a hovering full-scale quadcopter is associated with a self-organizing process in which the individual rotor vortices synchronize their freq…

Lagrangian Curvature Statistics from Gaussian Subensembles in Turbulent Flows
Yasmin Hengster, Johannes Bosbach, Daniel Schanz +2
A salient feature of fully turbulent flows far from onset is the intermittent occurrence of extreme fluctuations at small spatial and temporal scales. These have a qualitative and…

Effects of anisotropy on the geometry of tracer particle trajectories in turbulent flows
Yasmin Hengster, Martin Lellep, Julian Weigel +9
Using curvature and torsion to describe Lagrangian trajectories gives a full description of these as well as an insight into small and large time scales as temporal derivatives up…
