International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Large-eddy simulations of high Reynolds number jets with a suitable subgrid-scale model for solver dependency study [PDF]
, 2016 Large-eddy simulations are performed of a turbulent round jet at Ma = 0.5 and 0.9. The solver dependency is explored on computationally affordable grids of 5 and 20 million grid points, by taking advantage of the consistency of the subgrid-scale ...

Coupling OpenFOAM with external simulation codes using OpenFOAM-preCICE
, 2022 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
Wave, 2021 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 ...
