Numerical Simulation of the Dispersion of Exhaled Aerosols from a Manikin with a Realistic Upper Airway

Atmosphere, 2022
Basic analysis of the flow field and aerosol deposition under different conditions when a spreader contains an upper airway tract is important to accurately predict the transmission of virus-laden aerosols.

Experimental Investigation of a Micro Turbojet Engine Chevrons Nozzle by Means of the Schlieren Technique

Inventions, 2023
In connection with subsonic jet noise production, especially regarding the hot jet from a micro turbojet engine, we encountered a lack of recent high-resolution data in the literature describing the flow field using experimental validation through ...

Erosion Mechanism of a Cavitating Jet on Groove Roughness

Fluids, 2020
The erosion behavior of a cavitating jet on groove roughness was investigated experimentally using mass-loss characteristics, scanning electron microscopy (SEM) observation, time-resolved shadowgraph, and schlieren flow visualizations.

Schlieren Images of Negative Streamer and Leader Formations in CO₂ and a CF₃I-CO₂ Electronegative Gas Mixture

Applied Sciences, 2020
In electrical networks, SF6 gas is currently used to insulate high-voltage equipment, however, due to its high environmental impact, new alternatives such as CO2 and electronegative gas mixtures such as CF3I-CO2 are being trialled to replace SF6 and ...

State of the art of quantitative schlieren systems [PDF]

INCAS Bulletin
The present paper details the recent advances in three schlieren visualization methods, considering only those applied to obtain values of gas-dynamic parameters of the phenomenon, namely SIV (schlieren image velocimetry), CCS (color-calibrated schlieren)

Schlieren-Bound Magmatic Structures Record Crystal Flow-Sorting in Dynamic Upper-Crustal Magma-Mush Chambers

Frontiers in Earth Science, 2020
The size, longevity, and mobility of upper-crustal magma mushes, and thus their ability to mix and interact with newly arriving magma batches, are key factors determining the evolution of magma reservoirs.

Co-cultivation is a powerful approach to produce a robust functionally designed synthetic consortium as a live biotherapeutic product (LBP)

Gut Microbes, 2023
The success of fecal microbiota transplants (FMT) has provided the necessary proof-of-concept for microbiome therapeutics. Yet, feces-based therapies have many associated risks and uncertainties, and hence defined microbial consortia that modify the ...
