(1). During an experimental procedure of measurement of electrical resistivity, the electrical contact of electrodes to the conductive fluid (water) is rarely preserved to low water saturations, specifically for intermediate wet cores (Longeron et al., 1989a, Longeron et al., 1989b; Sondena ...
2.4. Thin film heater and temperature measurement The porous surface is heated by a thin film resistor consisting of a titanium-platinum bilayer (25 nm titanium adhesion layer and 120 nm platinum layer) with an area of 5 mm x 5 mm directly opposite the textured surface. To ensure that the...
In this contribution, we develop a microfluidic setup that allows for the simultaneous measurement of the inlet pressure during immiscible displacement within 2D PDMS porous-like domains at extremely high accuracy (i.e.\(\pm 20 {\rm Pa}\)which is sufficient for resolving both capillary and visco...
In this chapter we focus on the equation that expresses the first law of thermodynamics in a porous medium. We start with a simple situation in which the medium is isotropic and where radiative effects, viscous dissipation, and the work done by pressure
1c). The mercury intrusion capillary pressure measurement (MICP) employs a pressurized chamber to force mercury into the porous materials, where the volume of that mercury enters the pores is related to pore volume. Based on the assumption of cylindrical pores, the pore size distribution can be...
The measurement of some properties such as total porosity, microporosity and macroporosity can be used to infer the quality of the soil structure (Hillel, 2004). Total porosity is defined by the ratio between the volume of pores and the sample total volume. Traditionally it can be determined ...
It is rather easy to measure the length and diameter of a pipe and compute its flow capacity as a function of pressure. However, in porous media, the flow is different in that there are no clear-cut flow paths that lend themselves to measurement. The analysis of fluid flow in porous ...
of sintered porous PTFE in the manner described herein. The oil capillarity measures the capacity of the material to draw oil through by capillary action and is thus a measurement of the ability of the material to deliver liquid release oil to the roll of the fuser system of a copying ...
