Comparative assessment of volume‐of‐fluid (VOF) multiphase solvers for viscoplastic flow over grooved patterned surfaces

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5892-5909, November 2026.
Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

A Semi‐Resolved LES‐DEM Framework for Turbulent Bedload Transport From Saltation to Sheet‐Flow Regimes

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Bedload transport widely occurs in natural environments and encompasses flow regimes from saltation to sheet‐flow, with markedly different fluid‐particle interaction characteristics. Understanding these mechanisms requires a numerical tool capable of capturing both the turbulence and fluid‐particle interactions, for which challenges exist due ...

A Numerical Study on the Motion of Snow Aggregates Freely Falling in Air

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract This paper reports the results of the first quantitative study on the flow fields of freely falling snow aggregates. The motions are investigated by performing numerical simulations of four snow aggregate models consisting of 2, 3, 4, and 5 conformally shaped dendrites of different sizes.

Ontologies for Sustainability: Theoretical Challenges

open access: yesSustainable Development, Volume 34, Issue 5, Page 6833-6846, September 2026.
ABSTRACT The lack of sustainable practices in key sectors of human societies is a global concern, posing threats for the whole planet. This paper provides the first review of ontologies for sustainability efforts, outlining their roles in assessing and advancing such efforts. Section 2 outlines three major challenges associated with sustainability: (1)

Characterizing the Forearc Basement and Subducting Structures of the Northern Ecuadorian Margin

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present 2D P‐wave velocity (Vp) models from the northern Ecuadorian subduction zone, north of the Carnegie Ridge. Data were collected during the HIPER2 3D wide‐angle seismic experiment, both onshore and offshore. Key seismic profiles were manually picked to determine P‐wave first‐arrival times, which were used for a traveltime tomographic ...

Pore‐Scale Study of Fluid‐Fluid Interfacial Area During Primary Drainage in Porous Media

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract We performed pore‐scale numerical simulations using the volume of fluid (VOF) method to investigate how displacement regimes, geometric disorder, and wettability influence fluid‐fluid interfacial area awn $\left({a}_{wn}\right)$ during primary drainage. We partitioned awn ${a}_{wn}$ into two components: the advancing front awn,f $\left({a}_{wn,
