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 ...

Professor Kim, considering the mixing and spreading mechanism, used various flow visualization techniques and equipment for capturing high speed images in his experiment.

He recently turned his expertise toward masks to help develop new ways to measure and improve their performance. Staymates created two videos using different flow visualization techniques.

The current study applies flow visualization techniques and anemometry to investigate the dispersal of exhaled air in terms of the pattern of spread and the velocity at which the air escapes.

Laser Doppler velocimetry (LDV) has been used to make ensemble averaged and root mean square (RMS) velocity measurements at a crank shaft speed of 675 rpm in a motored rotary engine assembly. Sapphire ...

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

We have developed a simple and lower cost mixed air flow fan with guide vanes on the blade surfaces for use in automotive engine cooling. Through investigation of the fan performance and flow ...
