Sizing of reactive silencers with non-perforated tubes with the simulation software SILDIS®
Sizing of reactive silencers with non-perforated tubes is a subject that acousticians are far from having covered.
The approach for the prediction of acoustic and aerodynamic performance of reactive silencers, involving the consideration of various input data (e.g. thermodynamic parameters, noise reduction criteria, back pressure criteria, size of the soundproofing device), is computationally intensive, what is a serious obstacle for the design of tailor made solutions in a short period of...
Integration of the prediction of piping systems discharge parameters to the simulation software SILDIS®
The prediction of piping systems discharge parameters is a necessity for the expert in industrial acoustics.
The sizing of silencers for industrial fluids networks, whether or not involving the noise prediction of specific equipment e.g. control valves , safety valves  requires having, as available input data, indicators such as the status (choked or non-choked) of the discharge line end, the pressure at discharge line end or the discharge capacity (the flow rate) of fluid of which...
Integration to the simulation software SILDIS® of the calculation of flow indicators for the prediction of industrial processes control valves aerodynamic noise
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® , 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...
