Description of laminar-turbulent transition of an airfoil boundary layer measured by differential image thermography using directed percolation theory
Tom T. B. Wester, Joachim Peinke, Gerd Gülker
The study presented here addresses the challenging problem of laminar-turbulent flow transition in boundary layers. Directed percolation theory has emerged as a promising approach…
Hybrid time series from PIV for characterization of turbulent flow fields: ASTRA -- Approach using Spatially and Temporally Resolved Advection
Tom T. B. Wester, André Fuchs, Joachim Peinke +1
Particle Image Velocimetry (PIV) has become increasingly popular to study structures in turbulent flows. PIV allows direct extraction and investigation of spatial structures in the…
How to design a 2D active grid for dynamic inflow modulation
Tom T. B. Wester, Johannes Krauss, Lars Neuhaus +4
Wind turbines operate under constantly changing turbulent inflow conditions. In the rotating system, wind gusts lead to variations in the angle of attack at local blade segments re…
Dynamic stall of an airfoil under tailored three-dimensional inflow conditions
Dominik Traphan, Tom T. B. Wester, Matthew Melius +3
Rotor blades of wind turbines in the atmospheric boundary layer regularly experience the aerodynamic phenomenon of dynamic stall consisting of a temporary overshoot of lift and det…
Insights into the Periodic Gust Response of Airfoils
Nathaniel J. Wei, Johannes Kissing, Tom T. B. Wester +6
The unsteady lift response of an airfoil in a sinusoidal gust can be modeled by two transfer functions: the first-order Sears function and the second-order Atassi function, albeit…
Directed percolation in aerodynamics: resolving laminar separation bubble on airfoils
Dominik Traphan, Tom T. B. Wester, Gerd Gülker +2
In nature, phase transitions prevail amongst inherently different systems, while frequently showing a universal behavior at their critical point. As a fundamental phenomenon of flu…
