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 ...

Surface and off-surface flow visualization techniques have been used to visualize the three-dimensional separated flows on the NASA F-18 high alpha research vehicle (HARV) at high angles of attack.

The global ocean is the Earth's heating and cooling system, pushing balmy tropical waters toward the poles and bringing back colder, nutrient-rich waters. But modeling this system is extremely complex ...

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 ...

Four-dimensional flow MRI reveals that blood flow in an artificial heart resembles that in a healthy human heart ...

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 ...

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.

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 ...
