TL;DR: A verification and validation study was performed using the open source computational fluid dynamics solver OpenFOAM version 2.0 for incompressible bluff body fluid flows, which shows mostly monotonic convergence with averaged grid uncertainty.

TL;DR: In this article, the URANS computations of standard maneuvers are performed for a surface combatant at model and full scale using CFDShip-Iowa v4, a free surface solver designed for 6DOF motions in free and semi-captive problems.

TL;DR: In this article, various modeling, numerical methods, and high performance computing approaches for computational ship hydrodynamics are evaluated thereby providing a vision for the development of the next-generation high-fidelity simulation tools.

TL;DR: In this paper, a two-point multilayer wall function is used to compute model and full-scale ship flows with wall roughness and pressure gradient effects, which is validated for smooth flat-plate flows at Reynolds numbers up to 10 9, and applied to the Athena R/V for resistance, propulsion, and seakeeping calculations and to fully appended DTMB 5415 for a maneuvering simulation.

TL;DR: This paper investigates a recently proposed dynamic hybrid RANS-LES framework using a general-purpose finite-volume flow solver, allowing coupling of any selected RANS model with any selected LES model and containing no explicit grid dependence in its formulation.
