-Open cell metal and carbon foams have unique properties that make them very attractive to a wide range of engineering applications such as heat transfer in heat exchanger analysis and design, petroleum engineering, aerospace engineering, chemical engineering, fuel cell technology, filtration, and flow stabilization. The study of heat and fluid flow through such foams or porous media depends on a series of unique concepts such as porosity, permeability, and volume averaged pressure drop and it is very essential that these concepts should be properly understood. This paper reports the experimental measurements of the porosity and permeability of open cell aluminum and reticulated vitreous carbon (RVC) foams of pore sizes varying from10 ppi (pores per inch) to 100 ppi. An experimental setup is developed and measurements are taken.

“…The porosity of the specimens was obtained from the micro-CT data (100 -BV/TV) and validated using Archimedes' suspension method of measuring volume [16] which was performed using six cubes (2 × 2 × 2 cm 3 ) with the same structure as the Osteo surrogates. One of the six cubes was also used to measure the permeability of the Osteo structure using Darcy's law [17,18].…”

“…The literature on tortuosity, and many other related topics, up to the early 1970's, is summarized in the book of Bear [4]. Bear notes that Carmen [12] proposed a tortuosity factor as an effect on the velocity and on the driving force and he defined tortuosity as dependent upon (L e /L) 2 , where L is the straight-line length (end to end) of a tortuous total of length L e . The concept of a closed tortuous tube as a unit model for the fluid passage pore structure in a porous medium was subsequently widely used in many formulas for tortuosity [4,32].…”

“…The Carcione tortuosity T CF of the fluid is the mean square deviation of the microscopic field of the fluid from the solid mean field, normalized by the square of the relative field between the solid and fluid constituents. The induced or added mass of Biot [1][2][3], ρ 12 , is related to these tortuosities by…”

The multiple definitions of permeability and tortuosity employed by investigators modifying the basic equations of dynamic poroelasticity pose a problem as some resulting analyses produce results conflicting with those of other investigators. When the same words are used to describe different definitions of different concepts, the problem is compounded. These problems were highlighted in recent applications of acceleration wave analyses of dynamic poroelasticity. Wilmanski [40] and Coussy [14] applied acceleration wave analysis to their own systems of dynamic poroelastic equations and found contradictory results. In one case the wave speed depends upon tortuosity and in the other case a dependence upon permeability (and tortuosity) was not allowed. This means that acceleration waves in the Wilmanski [40] analysis cannot exhibit dispersion at lower frequencies. Harmonic wave analyses applied to the same systems of dynamic poroelastic equations predict a dependence of wave speed upon permeability. The acceleration wave analysis of a system of dynamic poroelastic equations is dependent upon the definitions of tortuosity used by the investigators. Wilmanski [40] and Coussy [14] each used their own definition of tortuosity.
