Numerical Analysis of a Single Bubble by VOF Method.
JSME International Journal Series B, 1993 In order to examine the feasibility of direct simulation of bubbly flow, the applicability of the VOF (volume of fluid) method to analyses of a single rising bubble was examined in this study. Calculated bubble shapes and terminal velocities under wide ranges of Eotvos number and Morton number were compared with the experimental data summarized by ...

Modeling Interactions and Dynamic Saturation Processes in Karst Media
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract The simulation of karst aquifers is highly challenging due to complex conduit‐matrix interactions. This study utilizes KarstFOAM, a high‐fidelity, physics‐based numerical model, to address these challenges. KarstFOAM integrates (a) a unified single‐domain Forchheimer–Darcy–Brinkman–Stokes (FDBS) formulation that transitions naturally across ...

Numerical investigation of air-entrainment in skimming flow over stepped spillways
Theoretical and Applied Mechanics Letters, 2016 As a widely used flood energy dissipator, the stepped spillway can significantly dissipate the kinetic or hydraulic energy due to the air-entrainment in skimming flow over the steps.

A Hybrid Continuum Surface Force for the Three-Phase Vof Method
, 2023 We propose a hybrid continuum surface force (CSF) formulation to model the interface interaction within the three-phase volume of fluid (VOF) method. Instead of employing the height function globally, we compute the curvature based on a smooth fraction function near the region of the triple contact line.

Role of Dead‐End Regions and Transmitting Pores in Mixing and Reactivity in Unsaturated Porous Media
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Mixing‐limited reactions in unsaturated porous media are controlled by complex pore‐scale processes arising from air and water phases coexistence. Decreasing water saturation increases flow heterogeneity, creating preferential flow paths and dead‐end regions (DER) that alter solute distribution and reaction efficiency.

Effect of Submerged Vegetation on Water Surface Geometry and Air–Water Momentum Transfer
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Understanding how submerged vegetation modifies the water surface is crucial for modeling momentum exchange between shallow waters and the atmosphere. In particular, quantifying its impact on the equivalent aerodynamic roughness of the water surface is essential for improved boundary‐layer parameterization in oceanic and atmospheric models. In
