Transport properties of real metallic foams

Journal of Colloid and Interface Science, 2010
Three dimensional samples of three different foams are obtained by microtomography. The macroscopic conductivity and permeability of these foams are calculated by three different numerical techniques based on either a finite volume discretization or Lattice Boltzmann algorithm.

Comparison of Single-Phase Convection in Additive Manufactured Versus Traditional Metal Foams

Journal of heat transfer, 2020
Metal foams have been often used for thermal management due to their favorable characteristics including high specific surface area (SSA), high thermal conductivity, and low relative density.

Interfacial and rheological properties of long-lived foams stabilized by rice proteins complexed to transition metal ions in the presence of alkyl polyglycoside.

Journal of Colloid and Interface Science, 2022
HYPOTHESIS Transition-metal coordination complexes are hopeful to make advanced structural materials, since the metal-coordination bonds, unlike typical covalent bonds, can regenerate after rupture, allowing for dynamic, tunable, and reversible ...

Thermal conduction in open-cell metal foams: Anisotropy and Representative Volume Element

International journal of thermal sciences, 2019
It is well known that the manufacturing process of open-cell foams slightly elongates their struts in one direction, thus making them anisotropic; in turn, anisotropy affects foam characteristics.

A comparative study of PCM melting process in a heat pipe-assisted LHTES unit enhanced with nanoparticles and metal foams by immersed boundary-lattice Boltzmann method at pore-scale

International Journal of Heat and Mass Transfer, 2018
Latent heat thermal energy storage (LHTES) has attracted lots of attention due to its nearly constant working temperature and large thermal energy storage density.

Fracture of Metal Foams: A Discrete Modelling Approach

2008
A discrete model based on two-dimensional Voronoi tessellation has been used to study damage and fracture in open-cell metal foams. The present study focuses on elastic-fracture behaviour of the foam. A competition mechanism among various damaging struts leading to damage localization and formation of a fracture band has been observed.
