Silencers - Modeling the acoustic behavior of curved absorbers
Modeling the acoustic behavior of curved absorbers is of the greatest interest in terms of acoustics.
Indeed, curved absorbers occupy a place of choice among the soundproofing components since they constitute the lining of the cylindrical dissipative silencers, often used in the context of industrial sound insulation projects (e.g. for fan discharge, downstream of the diffusers of vent silencers for pressurized gas, downstream of reactive mufflers for thermal engine exhaust lines) and for...
Simulation of acoustic and aerodynamic performance of silencers with CFD, FEM & BEM calculation tools
Computational Fluid Dynamics (CFD), to which reference is often made by using english wording, is a computational method for studying the motion of a gas or of a liquid, or its effects, by the numerical resolution of the equations that govern its behavior, considering a mesh of the studied system.
The Finite Element Method (FEM) and the Boundary Element Method (BEM), to which reference is also often made by using english wording, are intended to numerically solve equations such as those...
Room acoustics simulation by ray tracing with ITS
Ray tracing is a method for calculating the path of acoustic waves of which applications are possible for enclosed spaces, industrial or not, in relation to acoustical quality consideration.
Input data for such computations are obviously the geometry of the considered space and the distribution of absorbing surfaces for which material quantity, sound absorption coefficient (and sometimes scattering coefficient) one should account, being either floor or walls or roof (whatever its shape is), or...
