Computation of silencers with alternate splitter baffles orientation

Details

Reducing noise in industrial air networks is an issue with considerable technical and financial stakes, particularly in the case of large cross sections (often rectangular or even square) through which a fluid is transported with a very high flow rate, such as for example in the case of projects including large diameter fans (of the order of 10 m for some cooling towers) or turbomachines (large capacity compressors, combustion turbines even of average power) with regard to both air intake and...

Acoustics - Boosting silencer performance with SILDIS® software

Details

In the soundproofing sector, the selection (from a range of standardized products) or the development (custom-made) of silencers is a recurring engineering task in various contexts, the acoustic and aeraulic (aerodynamic) performance of such noise reduction devices being both multifactorial and antagonistic. In this field, experience then plays - of course - an important role, and appropriate tools determine the best technological choices.

The combination of geometric parameters e.g. thickness...

General information relating to the performance of baffle (splitter) silencers

In the building sector or in an industrial context, noise limitation in air networks is often achieved by means of baffle (splitter) silencers i.e. constructions with a casing (in some cases: constituted by a duct, or an existing chimney flue) and, inside, with sound-absorbing elements (wool or foam with various surfacings and protections depending on the...
