Depth‐Resolved Surfzone Wave and Roller Transformation

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract The vertical structures of cross‐shore wave, roller, and other momentum forcing terms are examined using a two‐phase Reynolds‐averaged Navier‐Stokes model driven with field and laboratory measured waves and bathymetry. Modeled wave height, setup, and undertow agree well with field observations along a cross‐shore transect extending from the ...

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

Numerical Analysis of a Single Bubble with VOF Method.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991
In order to examine the feasibility of direct simulation of bubbly flows, the applicability of the VOF (volume of fluid) method to the analyses of a single rising bubble was examined in this study. Calculated bubble shapes and terminal velocities under wide ranges of Eotvos number and Morton number were compared with the experimental data summarized by

VOLVOF: An update of the CFD code, SOLA-VOF [PDF]

, 1999
The SOLA-VOF code developed by the T-3 (Theoretical Physics, Fluids) group at the Los Alamos National Laboratory (LANL) has been extensively modified at the Oak Ridge National Laboratory (ORNL). The modified and improved version has been dubbed ''VOLVOF,'' to acknowledge the state of Tennessee, the Volunteer state and home of ORNL.

On the closure requirement for VOF simulations with RANS modeling

, 2019
The volume of fluid (VOF) method is increasingly used in computational fluid dynamics (CFD) simulations of turbulent two-phase flows. The Reynolds-Averaged Navier-Stokes (RANS) approach is an economic and practical way for turbulent VOF simulations. Even though RANS-VOF simulations are widely conducted, the underlying physics is barely discussed.
