Propagation of Pressure Perturbations in a Porous Medium Saturated with Bubbly Liquid [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2015
Wave processes in a porous medium saturated with bubbly liquid are numerically investigated. The nonlinearity of gas constitutive and Rayleigh–Lamb equations for bubble oscillations is taken into account.

Radiation and Flow Through a Porous Medium

open access: yesJournal of Porous Media, 2001
Flow through a porous medium in the presence of heat transfer has been analyzed. Special studies can be found in Nield and Bejan (1998). Recently Raptis (1998) studied the steady flow of a viscous fluid through a porous medium bounded by an infinite plate in the presence of thermal radiation in the fluid when the porosity of the porous is very high ...

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Determination of the effective thickness of a porous electrode in a flow-through reactor; effect of the specific surface area of stainless steel fibres, used as a porous cathode during the deposition of Ag(I) ions.

open access: yes, 2008
This study discusses the use of potential distribution analysis during the deposition of metal ions, at limiting current conditions and determines the optimum electrode thickness at which no hydrogen evolution occurs.

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Processing and fluid flow characteristics of hot isostatically pressed porous alumina for aerostatic bearing applications [PDF]

open access: yes, 1996
Despite their well known superior load and stiffness characteristics, the wide-spread use of porous aerostatic bearings in preference to other bearing types has been hampered by difficulties in controlling the permeability of the porous material during

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Stability of magnetohydrodynamic flow of viscous fluid in a horizontal channel occupied by a porous medium. [PDF]

open access: yes, 2014
. A study is made of the influence of a coplanar magnetic field on the linear stability of a electrically conducting fluid flowing between two infinite parallel fixed plates in a porous media using the energy method.

Gas-phase and heat-exchange effects on the ignition of high- and low-exothermicity porous solids subject to constant heating

open access: yes, 2006
This article investigates the ignition of low-exothermicity reactive porous solids exposed to a maintained source of heat (hotspot), without oxygen limitation.
