Integration of the prediction of the sound power radiated by the casing of components of duct systems to the simulation software SILDIS®

For components of ducts systems such as those to be envisaged for air conditioning systems, ventilation systems for premises or enclosures (generally: whenever the installation of a fan is to be considered), for exhaust lines of combustion engines or gas turbines, etc. ... , the noise transmitted upstream or downstream of components (depending on flow direction) is not (in many cases) the only potential source of sound nuisance to consider.

Indeed, the noise radiated by the casing of...

Integration of the prediction of the acoustic performance of straight ducts to the simulation software SILDIS®

Straight ducts are components which are often present in duct systems such as those to be envisaged for air conditioning systems, ventilation systems for premises or for enclosures (in general: each time the installation of a fan is to be envisaged), exhaust lines for thermal engines or gas turbines, etc ... for which they are (among others) the basis for the construction of stacks.

The acoustic performance of straight ducts must be accounted for the purpose of the design of equipments for...

Integration of the sizing of rectangular silencers made of splitters (baffles) with a low total pressure loss to the simulation software SILDIS®

A low total pressure loss is often a major qualitative criterion for a silencer (in particular: rectangular), influencing its dimensions, and therefore its price.

Rectangular silencers with splitters (baffles) are the basis for many applications related to soundproofing: dissipative silencers, resonators, etc ... . Their total pressure loss (sometimes referred to as back pressure) is a key feature for the design of silencers because it affects in particular the size of soundproofing equipment...
