Surface homogenization of an array of Helmholtz resonators for a viscoacoustic model using two-scale convergence
Kersten Schmidt, Adrien Semin
We derive the weak limit of a linear viscoacoustic model in an acoustic liner that is a chamber connected to a periodic repetition of elongated chambers -- the Helmholtz resonators…
Homogenization of the time-dependent heat equation on planar one-dimensional periodic structures
Matko Ljulj, Kersten Schmidt, Adrien Semin +1
In this paper we consider the homogenization of a time-dependent heat conduction problem on a planar one-dimensional periodic structure. On the edges of a graph the one-dimensional…
On liners viscoacoustic impedance boundary conditions for an array of Helmholtz resonators in 3D
Adrien Semin, Kersten Schmidt
The present work deals with the resolution of the Linearized Navier-Stokes problem in a domain made of an array that consists into a repetition of elongated resonators connected to…
On impedance conditions for circular multiperforated acoustic liners
Kersten Schmidt, Adrien Semin, Anastasia Thöns-Zueva +1
Background: The acoustic damping in gas turbines and aero-engines relies to a great extent on acoustic liners that consists of a cavity and a perforated face sheet. The prediction…
Multiharmonic analysis for nonlinear acoustics with different scales
Anastasia Thoens-Zueva, Kersten Schmidt, Adrien Semin
The acoustic wave-propagation without mean flow and heat flux can be described in terms of velocity and pressure by the compressible nonlinear Navier-Stokes equations, where bounda…
On the homogenization of the Helmholtz problem with thin perforated walls of finite length
Adrien Semin, Bérangère Delourme, Kersten Schmidt
In this work, we present a new solution representation for the Helmholtz transmission problem in a bounded domain in with a thin and periodic layer of finite length.…
