Stability and Instability of Time‐Domain Boundary Element Methods for the Acoustic Neumann Problem

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT This work presents a stable time‐domain boundary element method for the acoustic wave equation in three‐dimensional unbounded domains. Other formulations of time‐domain boundary element methods based on retarded potential operators are known to exhibit stability issues, which often hinder their use in industrial contexts.

Quasi‐4‐Day Waves During the 2018/2019 SSW and Their Coupling to the Ionosphere Based on Whole Atmosphere Data Assimilation

Space Weather, Volume 24, Issue 3, March 2026.
Abstract A strong westward zonal wavenumber‐2 quasi‐4‐day wave (Q4DW) during the 2018/2019 Northern Hemisphere sudden stratospheric warming (SSW) is both captured by Aura Microwave Limb Sounder (MLS) observations and our new whole neutral atmosphere data assimilation system.

Modeling the Drying Process of CO2‐Water in Porous Media With a Novel Volume‐of‐Fluid Lattice Boltzmann Model

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Lattice Boltzmann (LB) modeling has been extensively applied to porous media processes, including evaporation. Former pore‐scale LB models for evaporation rely on oversimplified assumptions, such as matched viscosities. However, in subsurface CO2 ${\text{CO}}_{2}$–brine systems, the viscosity ratio can exceed 100 under relevant temperature ...

Two New Analytical Models for Three‐Dimensional Transport in a Confined Aquifer With a Permeable Reactive Barrier: A New Adsorptive‐Reactive Robin Matching Condition

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Existing analytical models for permeable reactive barriers (PRBs) treat an upgradient aquifer formation with contaminant sources as either a Dirichlet or Robin boundary condition specified at the upgradient face of the PRB. This study develops two new analytical models for three‐dimensional transport in a confined aquifer with a PRB. One model

Residual NAPL Intermittent Expulsion With Increasing Freeze–Thaw Cycles in Saturated Porous Media: Findings From a 2.5‐D Microfluidic Platform

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract In this study, we developed a 2.5‐D microfluidic experimental platform that enables nondestructive visualization of pore‐throat microstructures and the migration processes of residual non‐aqueous phase liquids (NAPL) within a three‐phase system (water–ice–NAPL) under freeze–thaw conditions.
