Integration of the prediction of industrial processes control valves aerodynamic noise to the simulation software SILDIS®
- Details
Predicting aerodynamic noise from industrial process control valves is no easy task.
In many installations in the chemical industry and in some power plants, aerodynamic noise is emitted by control valves in various industrial processes.
This noise is partially transmitted through the walls of the valves and also (and mainly) propagates downstream of the valves, being then transmitted by the pipes walls of networks, of more or less complex geometry (depending on the site constraints)
Integration of the sizing of silencers made of discontinued splitters (baffles) to the simulation software SILDIS®
- Details
Rectangular silencers with splitters (baffles) are the basis for many applications related to soundproofing when it is desired to limit the propagation of noise through openings with a circulating fluid. In many common cases (e.g. air conditioning networks, ventilation of equipment premises or of other rooms, ventilation systems for enclosures), splitters are most of the time continuous, i.e. with a height equal to that of the duct in which they are inserted, which facilitates their attachment...
Integration of the prediction of sound decay in enclosed spaces to the simulation software SILDIS®
- Details
Predicting sound decay in enclosed spaces remains a topical subject in Research and Development in acoustics.
Enclosed spaces are often an object of study in terms of acoustics when it comes to designing a soundproofing industrial building, an enclosure for a machine/ a process of big size, a test bench, a local for technical equipment or a room intended to house activities such as catering, education, sports and recreation (generally: whenever it is appropriate to consider the impact of...
