Numerical study of shock-wave mitigation through matrices of solid obstacles
TL;DR: In this paper, the authors analyze the control mechanism for shock propagation and attenuation in complex inhomogeneous and porous medium, particularly at lower effective flow area, where the frictional forces are expected to be important.
Journal ArticleDOI
The effect of fine particles on the drainage and coarsening of foam
TL;DR: In this paper, the effects of coal fly ash dispersed in foams on the coarsening and drainage dynamics are investigated in a free drainage experiment, where the growth rate of the bubbles is not significantly changed.
Journal ArticleDOI
Blast wave mitigation by dry aqueous foams
TL;DR: In this article, a multiphase formalism is used to model the dry aqueous foam as a dense non-equilibrium two-phase medium as well as its interaction with the high explosion detonation products.

Deformation and spallation of shocked Cu bicrystals with Σ3 coherent and symmetric incoherent twin boundaries
TL;DR: In this paper, the authors performed molecular dynamics simulations of Cu bicrystals with two important grain boundaries (GBs), Σ3 coherent twin boundaries (CTB), and symmetric incoherent twin boundary (SITB) under planar shock wave loading and revealed that the shock response (deformation and spallation) strongly depends on the GB characteristics.
Journal ArticleDOI
Macro-mechanical modelling of blast wave mitigation in foams. Part I: review of available experiments and models
TL;DR: A number of consistent methodologies for calculating this pressure reduction in foam are based on the effective gas flow model and their comparison with new results of blast wave experiments is presented in this article.

Characterization of polymeric structural foams under compressive impact loading by means of energy-absorption diagram
TL;DR: In this paper, the mechanical properties at room temperature of three polymeric foams (namely EPP, PUR and PS/PA) have been experimentally evaluated in both static and impact loading conditions.

A Generalized View of Foam Drainage: Experiment and Theory
TL;DR: In this paper, a new experimental method is presented using fluorescein dye to determine the spatial and temporal variations of the liquid volume fraction in aqueous foams This method was used for quantitative studies of liquid redistribution (drainage) in three types of experiments: forced, free, and pulsed drainage Characteristic quantities, such as the drainage velocity, show power-law dependences on experimental parameters that are inconsistent with traditional foam drainage models based on Poiseuille-type flow in the liquid-carrying channels (Plateau borders) of the foam.
Journal ArticleDOI
The foam drainage equation
TL;DR: In this paper, the authors review the history and recent development of this theory, analysing various exact and approximate solutions and relating them to each other, and propose a nonlinear partial differential equation for the foam density as a function of time and vertical position.

Liquid Flow through Aqueous Foams: The Node-Dominated Foam Drainage Equation
TL;DR: In this paper, the authors present an experimental study of forced drainage through a soap foam, where a constant liquid flux at the top of a dry foam produces a downwards traveling wave with a constant velocity and uniform liquid content.
