Abstract A permeability–porosity relationship is obtained for use in computational fluid dynamics (CFD) modelling of desalination and fluid flow in sea ice. This functional relationship is derived from laboratory data from the literature on unidirectional saltwater ice formation.

Cement and Concrete Research, 1972
Abstract The degree of hydration, the expansion during hydration, and the total porosity of low-porosity portland cement pastes were investigated at hydration times ranging from 1 hour to 180 days. The effects of the type of cement (Type I and II), the grinding aid, the surface of the cement, the water-cement ratio (0.2 and 0.3), and the temperature ...

Total porosity measurement in gas shales by the water immersion porosimetry (WIP) method
Fuel, 2014Abstract Over the past decade interest in shale properties has increased due to the commercial success of gas shale plays. Despite their commercial importance, porosity measurement from gas shale samples is still challenging due to their extremely low permeability and complex pore structure.

Electrical resistivity is one of the most commonly collected types of geophysical well log data used in groundwater investigations. Because electrical currents respond to changes in a formation's electrical properties and pore space characteristics, resistivity data are typically used together with gamma ray logs to qualitatively interpret changes in ...

Total voltage effect and electrode porosity
SPIE Proceedings, 1994`The total voltage effect'--being a main characteristic of vacuum insulation is explained from an earlier offered mechanism of vacuum insulation deterioration point of view. When an external electric field sagging in the negative electrode cracks and pores in their volume ionization processes occur.
