The acoustical behavior and the flow in a rectangular lined channel with grazing flow have been investigated. The liner consists of a ceramic structure of parallel square channels and is locally reacting. In the absence of flow, the liner has a classical behavior: the acoustic transmission coefficie

REFRACTIVE ENHANCEMENT OF A FLOW DUCT LINER PERFORMANCE
Predicted enhancement [1] of acoustic liner performance for sound propagating in the direction of the flow is reproduced experimentally by artificially thickening the boundary layer.

## Abstract A detailed analysis has been performed for a heterogeneous photocatalytic Taylor vortex reactor that uses flow instability to recirculate fluid continually from the vicinity of the rotating inner cylindrical surface to the stationary outer cylindrical surface of an annulus. A comprehens
This paper presents a unified algorithm for studying the eigenvalue problem of a lined duct using the homotopy method. Results from various validations show that the method developed in this work can provide accurate and reliable numerical solutions for sound-propagation computation. The investigati
## Abstract In this paper, combined convective heat transfer and nanofluids flow characteristics in a vertical rectangular duct are numerically investigated.
