1 Theory of sound propagation in superfluid - filled porous media
The theory of sound propagation in macroscopically isotropic and homogeneous porous media saturated with superfluid 4 He(so-called HeII) has been developed neglecting all damping processes. The case when the normal fluid component is locked inside a porous medium by viscous forces is investigated in detail. It is shown that in this case one shear wave and two longitudinal, fast and slow wave pr...
متن کاملSound Propagation in Porous Media: Upscaling Methods, Optimization and Validation
/department of mechanical engineering Introduction Noise reduction is a key issue for High-tech and high precision instruments. To reduce the noise levels emitted by internal or external sources, porous materials can be used for acoustic shielding. The acoustic wave penetrates into the pore network, and part of its energy is dissipated as heat by viscous friction and thermal-elastic damping, ma...
متن کاملSound Propagation in Capillary-tube-type Porous Media with Small Pores in the Capillary Walls
Sound propagation i gas-filled capillary-tube-type orous media was investigated. The capillary tubes were taken to be nominally straight with very small pores in the walls of the capillary tubes. The complex wave number and the characteristic mpedance of such media were evaluated. Application to ceramic samples having capillary pores with square cross sections and porous walls is developed as a...
متن کاملExplosion propagation in inert porous media.
Porous media are often used in flame arresters because of the high surface area to volume ratio that is required for flame quenching. However, if the flame is not quenched, the flow obstruction within the porous media can promote explosion escalation, which is a well-known phenomenon in obstacle-laden channels. There are many parallels between explosion propagation through porous media and obst...
متن کاملNonlocal theory of sound propagation in porous media: case of circular pores
Elaborating on a Maxwellian representation of longitudinal wave propagation in a viscothermal fluid, a general nonlocal macroscopic theory of sound propagation in homogeneous porous media saturated with a viscothermal fluid has been recently proposed. The present paper validates this new nonlocal Maxwellian theory by showing that, in the case of the propagation in straight circular tubes, it is...
