Effect of meniscus curvature on phase-change performance during capillary-enhanced filmwise condensation in porous media

open access: yesFrontiers in Thermal Engineering, 2023
Sustainably enhancing condensation heat transfer performance is a major challenge in thermal management and energy systems, since typical condensation enhancement methods (i.e., dropwise condensation with low surface energy coatings) have limited ...

Capillary-driven flow induced by a stepped perturbation atop a viscous film

open access: yes, 2012
Thin viscous liquid films driven by capillarity are well described in the lubrication theory through the thin film equation. In this article, we present an analytical solution of this equation for a particular initial profile: a stepped perturbation ...

Tests to characterize the behaviour of natural stone in contact with water

open access: yesMateriales de Construccion, 2002
This paper presents an experimental analysis of the stone behaviour in contact with water in the different construction uses. In any of these cases is analyse how the water penetrates into the material.

Review of Capillary Rise Experiments for Surface-Active Solutes in the Subsurface

open access: yesGeotechnics, 2022
Surface-active solutes that exist in the subsurface either naturally (humic acid) or as a result of anthropogenic activities (alcohols, surfactants, PFAS) alter the hydraulic and geotechnical properties of the unsaturated porous media.

Intrinsic versus super-rough anomalous scaling in spontaneous imbibition [PDF]

open access: yes, 2006
We study spontaneous imbibition using a phase field model in a two dimensional system with a dichotomic quenched noise. By imposing a constant pressure $\mu_{a}

Discrete modelling of capillary mechanisms in multi-phase granular media [PDF]

open access: yes, 2009
A numerical study of multi-phase granular materials based upon micro-mechanical modelling is proposed. Discrete element simulations are used to investigate capillary induced effects on the friction properties of a granular assembly in the pendular regime.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

Revisiting the applications of drainage capillary pressure curves in water-wet hydrocarbon systems

open access: yesOpen Geosciences, 2016
The main focus of the paper is to introduce a new approach at studying and modelling the relationship of initial water saturation profile and capillarity in water-wet hydrocarbon reservoirs, and describe the available measurement methods and possible ...
