Modeling of Gas Flow through Isotropic Metallic Foams

Experimental characterization of single and two-phase flow through nickel foams

“…Single-phase as well as two-phase flows are characterized. Relationships between fluid flow characteristic parameters and structural one, i.e., such as Ergun-like model, which have been recently reviewed by Dukhan and Patel (2008), Edouard et al (2008b) or Mahjoob and Vafai (2008), as well as development or improvement of hydraulic models for flow through metallic foams, as presented in Crosnier et al (2006), are here out of concern.…”

Measurement and prediction for air flow drag in different packing materials

“…The RUC foam model was developed to accurately predict flow behavior through foamlike porous media [3]. A typical example is a spongelike metallic foams.…”

Predicting the Permeability of Very Low Porosity Sandstones

“…The shaded volume in (a) represents the solid phase and in (b) it represents the fluid phase d s , respectively, denote the characteristic length of the RUC and the solid phase within the RUC. Woudberg et al (2006) improved the analytical modelling procedure of the granular RUC model and Crosnier et al (2006) improved the foam RUC model, based on the work of Lloyd et al (2004). Considering only low Reynolds number flow, ignoring the effect of gravity and assuming a steady single-phase flow of an incompressible Newtonian fluid with a uniform superficial velocity q through an unbounded porous medium, leads to the following very simple form of Eq.…”

“…5, for the foam RUC model as for the granular RUC model, the following expression for the foam permeability K foam is obtained (Crosnier et al 2006)…”

“…For the granular RUC model α = √ 2 (Woudberg et al 2006) and for the foam RUC model α = 1 (Crosnier et al 2006). Barber and Emerson (2002) proposed a slip boundary conditions in which the tangential shear stress τ t is linearly dependent on the tangential slip velocity at the pore wall u t , that is,…”
