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 ...

Dependence of Mineral Dissolution Rates on Two‐Phase Hydrodynamics in Single Pores
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Multiphase flow and mineral reactions co‐exist in many subsurface systems, and thus elucidating and quantifying the impacts of multiphase flow on mineral reaction rates are crucial. Our study established a benchmark experiment on calcite dissolution in cylindrical pores in slug flow, and performed a series of simulations using a validated pore‐

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.

Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 7, Page 3256-3273, May 2026.ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐

Surface Runoff Discrepancy in Urban‐PLUMBER Land Surface Models
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Enhanced surface runoff in urban environments reduces water availability and limits the evaporative cooling potential. We evaluate surface runoff in 18 urban land surface models (ULSM) in Urban‐PLUMBER for 6,570 rainfall events across 21 urban sites.
