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 ...

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.

A Mechanistic Model for Relative Permeability of Gas and Water Flow in Hydrate‐Bearing Porous Media With Capillarity

open access: yesWater Resources Research, 2019
Lack of mechanistic models to describe petrophysical properties of mobile phases in gas hydrate‐bearing sediments is one of the key challenges in accurately predicting gas production. The major drawback of empirical models that are used to fit a relative

A Reusable Capillary Flow-Driven Microfluidic System for Abscisic Acid Detection Using a Competitive Immunoassay

open access: yesSensors
Point-of-care (PoC) devices offer a promising solution for fast, portable, and easy-to-use diagnostics. These characteristics are particularly relevant in agrifood fields like viticulture where the early detection of plant stresses is crucial to crop ...

Global boundedness, interior gradient estimates, and boundary regularity for the mean curvature equation with boundary conditions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We obtain global estimates for the modulus, interior gradient estimates, and boundary Hölder continuity estimates for solutions u to the capillarity problem and to the Dirichlet problem for the mean curvature equation merely in terms of the mean ...

Experimental study on the rise of aqueous foams in vertical pipes

open access: yesFrontiers in Physics, 2022
In this paper we report experiments on the growth of dry foams and their rise in vertical pipes of different circular cross-sectional radii with length over diameter ratios in the interval 25 ≤ h/D ≤ 80 for applications in the study of fracture ...
