The influence of baffle fairings on the acoustic performance of rectangular splitter silencers [PDF]

open access: yes, 2005
A numerical model based on the finite element method is developed for a finite length, HVAC splitter silencer. The model includes an arbitrary number of bulk-reacting splitters separated from the airway by a thin perforated metal sheet and accommodates ...

Transmit-Array, Metasurface-Based Tunable Polarizer and High-Performance Biosensor in the Visible Regime

open access: yesNanomaterials, 2019
There are two types of metasurfaces, reflect-array and transmit-array,—which are classified on the basis of structural features. In this paper, we design a transmit-array metasurface for y-polarized incidence which is characterized by having a ...

A point collocation approach to modelling large dissipative silencers [PDF]

open access: yes, 2005
A numerical matching technique known as point collocation is used to model mathematically large dissipative splitter silencers of a type commonly found in HVAC ducts. Transmission loss predictions obtained using point collocation are compared with exact

Study on the Influence of Radial Inlet Chamber Splitter Blades on the Oblique Flow Compressor Performance

open access: yesEnergies, 2023
The oblique flow compressor is one of the important components in the compressed air energy storage (CAES) system. The structural shape of the radial inlet chamber (RIC) directly affects the compressor performance, and a reasonable RIC design should ...
