Flow visualisation and analysis techniques constitute a critical foundation for understanding complex fluid dynamics across a range of scientific disciplines, from climate research to engineering ...

Advanced experimental techniques have been developed for application in the Volkswagen automotive wind tunnels. Such procedures are: laser–Doppler anemometry (LDA) for detailed flow–field measurements ...

The airborne spread of pathogens has assumed great importance in the public eye following the onset of the coronavirus disease 2019 (COVID-19 pandemic). In an interesting new research paper published ...

Using high-speed video and schlieren imaging, a research engineer has created videos that show how air flows through masks with and without exhalation valves. Many people wear masks in public to slow ...

Figure 1. Illustration of unified image-based aerodynamic measurement techniques Image-based aerodynamic measurement techniques are being developed at Western Michigan University's applied ...

A new flow visualization study from the National Institute of Standards and Technology (NIST) starkly demonstrates why face masks with exhalation valves are not effective for slowing the spread of ...

Researchers have shown the ability of a micromilling machine to manufacture microchannels, and also the ability of a microfluidic device to perform partial separation of red blood cells from plasma.

Many people wear masks in public to slow the spread of COVID-19, as recommended by the Centers for Disease Control and Prevention (CDC). However, masks with exhalation valves do not slow the spread of ...
