SnapPINN: Pressure and Energy Dissipation Reconstruction from a Sparse and Noisy Velocity Snapshot
Robin Barta, Christian Bauer, Gholamhossein Bagheri
Reconstructing pressure and turbulence quantities from experimental velocity measurements is challenging, especially without time-resolved data. Furthermore, limitations such as lo…
FLASHμ: Fast Localizing And Sizing of Holographic Microparticles
Ayush Paliwal, Oliver Schlenczek, Birte Thiede +5
Reconstructing the 3D location and size of microparticles from diffraction images - holograms - is a computationally expensive inverse problem that has traditionally been solved us…
Highly Localised Droplet Clustering in Shallow Cumulus Clouds
Birte Thiede, Michael L. Larsen, Freja Nordsiek +3
The growth, lifetime, number density, and size of water droplets in warm atmospheric clouds determine the evolution, lifetime and light transmission properties of those clouds. The…
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…
Experimental measurement of respiratory particles dispersed by wind instruments and analysis of the associated risk of infection transmission
Oliver Schlenczek, Birte Thiede, Laura Turco +6
Activities such as singing or playing a wind instrument release respiratory particles into the air that may contain pathogens and thus pose a risk for infection transmission. Here…
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…
Respiratory aerosols and droplets in the transmission of infectious diseases
Mira L. Pöhlker, Ovid O. Krüger, Jan-David Förster +10
Knowing the physicochemical properties of exhaled droplets and aerosol particles is a prerequisite for a detailed mechanistic understanding and effective prevention of the airborne…
Risk assessment for airborne disease transmission by poly-pathogen aerosols
Freja Nordsiek, Eberhard Bodenschatz, Gholamhossein Bagheri
In the case of airborne diseases, pathogen copies are transmitted by droplets of respiratory tract fluid that are exhaled by the infectious and, after partial or full drying, inhal…
Population Distribution in the Wake of a Sphere
Taraprasad Bhowmick, Yong Wang, Michele Iovieno +2
The fluid physics of the heat and mass transfer from an object in its wake has much importance for natural phenomena as well as for many engineering applications. Here, we report n…
Supersaturation in the Wake of a Precipitating Hydrometeor and its Impact on Aerosol Activation
Taraprasad Bhowmick, Yong Wang, Michele Iovieno +2
The secondary activation of aerosols impacts the life cycle of a cloud. A detailed understanding is necessary for reliable climate prediction. Recent laboratory experiments demonst…
On the drag of freely falling non-spherical particles
Gholamhossein Bagheri, Costanza Bonadonna
We present a new general model for the prediction of the drag coefficient of non-spherical solid particles of regular and irregular shapes falling in gas or liquid valid for sub-cr…
