Tunable Sound Absorption via Evanescent‐Wave Coupling in Asymmetric Bilayer Metasurfaces

open access: yesAdvanced Science, EarlyView.
Tunable sound absorption is realized through a bilayer metasurface system governed by evanescent‐wave coupling. This work demonstrates that such evanescent‐wave coupling provides a controllable scattering channel that destructively interferes with the specular reflection.

Flow of Oldroyd-B fluid caused by a rotating disk featuring the Cattaneo-Christov theory with heat generation/absorption

International Communications in Heat and Mass Transfer, 2021
Abstract This article presented the Cattaneo-Christove heat and mass flux theories in the flow of Oldroyd-B fluid over a rotating disk. The flow configuration is due to the rotating as well as stretching of the disk. The heat generation/absorption and chemical reaction are also considered.

On the general theory of contained rotating fluid motions

Journal of Fluid Mechanics, 1965
A general linear theory is developed to describe the manner in which rigid fluid rotation is established from a prescribed initial state of motion in a container of arbitrary shape. The container rotates with uniform angular velocity and is filled with a viscous incompressible fluid.A new mean circulation theorem is proved and used to separate the flow
