At first glance, it seems that modern, inexpensive additive manufacturing (AM) technologies
can be used to produce innovative, efficient acoustic materials with tailored pore …

A novel multiscale porous composite structure is proposed in this paper, which combines the
advantages of two different micro-porous materials and distributed meso-pores to enhance …

This paper investigates acoustic wave propagation in gas-saturated permeable lossy
metamaterials, which have different types of resonators, namely, acoustic and elastic …

Multiscale oscillatory heat transfer and fluid flow of a gas in permeable media subjected to
acoustic wave excitation is investigated in this paper. The two-scale asymptotic method of …

The distribution of fiber diameters plays a crucial role in the transport and sound absorbing
properties of a three-dimensional random fibrous (3D-RF) medium. Conventionally, volume …

Herein, a zeolite@ mesoporous silica composite (Z@ MS) with a hierarchical porous
structure was synthesized and employed as the filling material in miniature loudspeakers …

This paper presents a mathematical model of a double poro-elastic medium derived by the
homogenization of a two-component periodically heterogeneous Biot continuum …

Upscaling the flow equations appears in many studies related to diffusion, heat conductivity,
and flows in porous media. Variable coefficients of the original fine-scale process …

This study investigates the influence of pore size polydispersity on the acoustic behavior of
high-porosity solid foams using numerical simulations. The effect of the size of the periodic …

We study the dynamics of Newtonian fluids subject to complex pressure gradients within
bent oscillating nanotubes. Pressure gradients with four different purely oscillatory time …
