2002 journal article

Acoustic streaming induced by ultrasonic flexural vibrations and associated enhancement of convective heat transfer

JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA, 111(2), 875–883.

By: B. Loh n, S. Hyun n, P. Ro n & C. Kleinstreuer n

MeSH headings : Acoustics; Hot Temperature; Models, Theoretical; Ultrasonics; Vibration
TL;DR: Acoustic streaming induced by ultrasonic flexural vibrations and the associated convection enhancement are investigated and it is observed that the streaming velocity decreases with the excitation frequency, and with an open-ended channel, a substantial increase in streaming velocity is observed from CFD simulations.

TL;DR: The UFW-based fan offers advantages over the conventional fan, such as silent operation, minimal heat dissipation, lack of wearing parts, and slim profile, which makes the fan an ideal candidate for cooling miniature parts in an enclosed workspace. (via Semantic Scholar)
