An experimental data-driven mass-spring model of flexible Calliphora wings
Hung Truong, Thomas Engels, Henja Wehmann +3
Insect wings can undergo significant deformation during flapping motion owing to inertial, elastic and aerodynamic forces. Changes in shape then alter aerodynamic forces, resulting…
Wavelet Adaptive Proper Orthogonal Decomposition for Large Scale Flow Data
Philipp Krah, Thomas Engels, Kai Schneider +1
The proper orthogonal decomposition (POD) is a powerful classical tool in fluid mechanics used, for instance, for model reduction and extraction of coherent flow features. However,…
Fluid-structure interaction using volume penalization and mass-spring models with application to flapping bumblebee flight
Hung Truong, Thomas Engels, Dmitry Kolomenskiy +1
Wing flexibility plays an essential role in the aerodynamic performance of insects due to the considerable deformation of their wings during flight under the impact of inertial and…
A mass-spring fluid-structure interaction solver: Application to flexible revolving wings
Hung Truong, Thomas Engels, Dmitry Kolomenskiy +1
The secret to the spectacular flight capabilities of flapping insects lies in their wings, which are often approximated as flat, rigid plates. Real wings are however delicate struc…
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…
