Pore-scale direct numerical simulation of Haines jumps in a porous media model

, 2020
Direct numerical simulations are presented for a porous media model consisting of two immiscible fluids, an invading and defending phase, in a two-dimensional micro-geometry filled with randomly sized and randomly distributed cylinders.

Numerical modelling of the filling of formworks with self-compacting concrete [PDF]

, 2010
This paper describes the numerical modelling of the flow of self-compacting concrete (SCC) in column and wall formworks during the filling process. It is subdivided in four main parts.

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.

Application of CLEAR-VOF method to wave and flow simulations

Water Science and Engineering, 2012
A two-dimensional numerical model based on the Navier-Stokes equations and computational Lagrangian-Eulerian advection remap-volume of fluid (CLEAR-VOF) method was developed to simulate wave and flow problems. The Navier-Stokes equations were discretized

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‐

The Effect of ‘Hydraulic‐Visual’ Interaction on the Intensity of Fish Schooling in the Upstream Movement of Juvenile Silver Carp

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study used juvenile silver carp as model organisms to investigate the combined effects of flow velocity, turbulence kinetic energy and visual cues from obstacles on fish schooling intensity. The experiments demonstrated that schooling intensity is a dynamic behavioural adjustment shaped by the integration of hydraulic constraints, energetic ...

Phase-field simulation of core-annular pipe flow

, 2019
Phase-field methods have long been used to model the flow of immiscible fluids. Their ability to naturally capture interface topological changes is widely recognized, but their accuracy in simulating flows of real fluids in practical geometries is not ...

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.

A Finite Element Method for Compressible and Turbulent Multiphase Flow Instabilities with Heat Transfer

Fluids
We present a new finite element framework for modeling compressible, turbulent multiphase flows with heat transfer. For two-fluid systems with a free surface, the Volume of Fluid (VOF) method is implemented without the need for interface reconstruction ...
