Investigating the in-/through-plane effective diffusivities of dry and partially-saturated gas diffusion layers [PDF]

, 2018
In this study, the effective oxygen diffusivity in the dry or partially-saturated gas diffusion layer (GDL) is numerically investigated by an oxygen diffusion model in GDLs reconstructed by a stochastic method.

Ocean Wave Modulation of Offshore Wind Turbine Loads and Wake

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT This study examines how wave‐induced modulation affects the operational performance and structural dynamics of fixed‐bottom offshore wind turbines operating under a neutral atmospheric boundary layer profile. To capture these effects accurately while maintaining computational efficiency, unsteady RANS modelling techniques are employed.

Microscopic seepage simulation of gas and water in shale pores and slits based on VOF

Open Physics
The microscopic pore-fracture structure and wettability have a significant influence on the two-phase seepage of shale gas and water. Due to the limitation of experimental conditions, the seepage patterns of gas and water in shale pores and slits under ...

New VOF interface capturing and reconstruction algorithms [PDF]

, 1999
Several new methods are presented for the capturing and tracking of material boundary interfaces. All methods belong to the general Volume Of Fluid (VOF) approach, and vary from simple flow aligned algorithms to more complex geometric modeling. The performance of the different methods is evaluated by solving the advection equations for a variant of the

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‐

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.

Large droplet impact on water layers [PDF]

, 2004
The impact of large droplets onto an otherwise undisturbed layer of water is considered. The work, which is motivated primarily with regard to aircraft icing, is to try and help understand the role of splashing on the formation of ice on a wing, in ...
