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 ...

Researchers are pioneering new ultrasound techniques that provide the first characterization of multidirectional blood flow in the heart. By focusing on fluid dynamics – specifically, the efficiency ...

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.

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 ...

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 ...

Daniel M. Nosenchuck's research interests include experimental and computational fluid mechanics, dynamic flow control and visualization, and advanced supercomputer architectures. His major ...

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 ...
