Inertial Effects on Fluid Flow Through Natural Porous Media
Abstract We investigated the nonlinear effects of gravity‐driven fluid flow through a two‐dimensional, moderately low‐porosity, packed bed of stubby stone grains in Darcy, and post Darcy regimes. We focused on preferential channel formation, tortuosity, spatial distribution of kinetic energy, and vortex formation.

This study presents a method combining coordinate interpolation and selective noise filtering to reduce surface roughness in medical image‐based geometries. Applied to carotid and cerebral arteries, it reduced roughness by 27%–32%, with minimal volume change and a 4.2% decrease in WSS, improving CFD accuracy for low‐resolution medical images.

Coupling OpenFOAM with external simulation codes using OpenFOAM-preCICE
Users of simulation codes often wish to extend simulations to include phenomena solved in OpenFOAM. Such problems appear in cooling devices, on flexible wings, or even in nuclear fusion reactors. The OpenFOAM-preCICE adapter allows users to quickly couple OpenFOAM to arbitrary other codes, bridging their communities, and opening new application ...

THE SIMULATION OF SKEG EFFECT TO BARGE RESISTANCE CALCULATION USING CFD-RANS OPENFOAM
The paper discusses the significance of different types of skegs in a barge toward the pressure, fluid velocity and the ship total resistance. There are three kinds of skeg configurations: barge without skegs, skegs without deflection, and skegs with ...
