Integration to the simulation software SILDIS® of the calculation of flow indicators for the prediction of industrial processes control valves aerodynamic noise
- Details
Flow indicators are fundamental for anyone working in the context of projects related to noise reduction of pressurized fluid networks.
The prediction of aerodynamic noise of various industrial process control valves is possible with the simulation software SILDIS® [1], given earlier developments, the calculation necessitating to have, as available input data, flow indicators that influence the intrinsic mechanical power, the dominant frequency of the noise and therefore the total internal...
Integration of the prediction of the spatial decay of speech in open spaces to the simulation software SILDIS®
- Details
Predicting the spatial decay of speech intelligibility in open spaces is a subject that acousticians are far from having covered, even though it constitutes a key step in many architectural acoustics projects.
Enclosed spaces are often an object of study in terms of acoustics and have been in the past the aim of the development of the Module 9 of SILDIS® software (prediction of sound decay in enclosed spaces) which does not, however, allow the consideration of screens such as barrier walls...
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)
