Statistics of fully turbulent impinging jets
Robert Wilke, Jörn Sesterhenn
Direct numerical simulations of sub- and supersonic impinging jets with Reynolds numbers of 3300 and 8000 are carried out to analyse their statistical properties. The influence of…
On the origin of impinging tones at low supersonic flow
Robert Wilke, Jörn Sesterhenn
Impinging compressible jets may cause deafness and material fatigue due to immensely loud tonal noise. It is generally accepted that a feedback mechanism similar to the screech fee…
Bumblebees minimize control challenges by combining active and passive modes in unsteady winds
Sridhar Ravi, Dmitry Kolomenskiy, Thomas Engels +4
The natural wind environment that volant insects encounter is unsteady and highly complex, posing significant flight control and stability challenges. Unsteady airflows can range f…
A Characteristic Dynamic Mode Decomposition
Jörn Sesterhenn, Amir Shahirpour
Temporal or spatial structures are readily extracted from complex data by modal decompositions like Proper Orthogonal Decomposition (POD) or Dynamic Mode Decomposition (DMD). Subsp…
