The Effect of Dynamic Capillarity in Modeling Saturation Overshoot during Infiltration

open access: yesVadose Zone Journal, 2019
Gravity-driven fingering has been observed during downward infiltration of water into dry sand. Moreover, the water saturation profile within each finger is non-monotonic, with a saturation overshoot at the finger tip.

Role of interfacial tension on wettability-controlled fluid displacement in porous rock: A capillary-dominated flow and how to control it [PDF]

open access: yes, 2023
Oil displacement by spontaneous imbibition is a capillary-governed process, in which wettability controls fluid displacement direction. Capillarity is a driving force to enhance oil displacement in water-wet system, while in oil-wet system capillarity is

A Novel Multipurpose Self-Irrigated Green Roof with Innovative Drainage Layer

open access: yesHydrology, 2023
Climate change is a significant problem that many countries are currently facing, and green roofs (GRs) are one of the suitable choices to confront it and decrease its impacts.

Correlations between water absorption, electrical resistivity and compressive strength of concrete with different contents of pozzolan

open access: yesRevista ALCONPAT, 2019
This research confronts the following concrete properties: water absorptions (by immersion and capillarity), electrical resistivity and compressive strength. Concrete mixtures with two types of cement were tested.

The laboratory investigation of the capillarity of various dental solutions at three temperature levels [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo
Introduction/Objective. Many oblong micro-spaces of less than 500 μm exist within oral cavity, such as dentine canalicular spaces, gaps, recesses, gingival sulcus etc. Since these spaces are susceptible to food and pathogenic microbe’s accumulation, most

Modeling unimodal/bimodal soil-water retention curves considering the influence of void ratio under capillarity and adsorption

open access: yesRock and Soil Mechanics, 2021
The constitutive relationship between suction and degree of saturation is of great significance for estimating the shear strength and deformation behavior of unsaturated soils.

Capillarity test monitored by X-ray computer tomography in sandstones. A comparative study with standard methods

open access: yesMateriales de Construccion, 2008
Computerized axial tomography studies were conducted to analyze water movements inside rocks (specifically in La Marina sandstone, used to build some of the historic monuments in Asturias, northern Spain).

Limewashes with Linseed Oil and Its Effect on Water and Salt Transport

open access: yesBuildings, 2022
Paints are the protective and aesthetic skin of buildings, so (re) painting is one of the most recurrent maintenance actions. Limewashes have been used since antiquity and are currently of high interest for both conservation and new construction, majorly

Impact of the Dissipation on the Nonlinear Interactions and Turbulence of Gravity-Capillary Waves

open access: yesFluids, 2022
Gravity-capillary waves at the water surface are an obvious example illustrating wave propagation in the laboratory, and also nonlinear wave phenomena such as wave interactions or wave turbulence. However, at high-enough frequencies or small scales (i.e.,
