Flight of a honeybee in turbulent wind
Bardia Hejazi, Christian Küchler, Gholamhossein Bagheri +1
In windy conditions, the air is turbulent. The strong and intermittent velocity variations of turbulence are invisible to flying animals. Nevertheless, flying animals, not much lar…
Face-masks save us from SARS-CoV-2 transmission
Gholamhossein Bagheri, Birte Thiede, Bardia Hejazi +2
We present results on the infection risk from SARS-CoV-2 under different scenarios based on measured particle size-dependent mask penetration, measured total inward leakage, measur…
On the risk of infection by infectious aerosols in large indoor spaces
Bardia Hejazi, Oliver Schlenczek, Birte Thiede +2
Airborne diseases can be transmitted by infectious aerosols in the near field, i.e., in close proximity, or in the far field, i.e., by infectious aerosols that are well mixed withi…
Using deformable particles for single particle measurements of velocity gradient tensors
Bardia Hejazi, Michael Krellenstein, Greg A. Voth
We measure the deformation of particles made of several slender arms in a two-dimensional (2D) linear shear and a three-dimensional (3D) turbulent flow. We show how these measureme…
Emergent scar lines in chaotic advection of passive directors
Bardia Hejazi, Bernhard Mehlig, Greg A. Voth
We examine the spatial field of orientations of slender fibers that are advected by a two-dimensional fluid flow. The orientation field of these passive directors are important in…
