A New Volume-Of-Fluid Method in Openfoam [PDF]
, 2017 To realise the full potential of Computational Fluid Dynamics (CFD) within ma- rine science and engineering, there is a need for continuous maturing as well as verification and validation of the numerical methods used for free surface ...

SIMPLIFIED VOLUME OF FLUID METHOD (SVOF) FOR TWO-PHASE FLOWS
TASK Quarterly, 2008 The PLIC approach has been usually used in recent implementations of the VOF method i.e. the interphasal surface is approximated by a plane with an arbitrary orientation with respect to the computational cell.

Adjoint complement to the volume-of-fluid method for immiscible flows [PDF]
Journal of Computational Physics, 2020 The paper is concerned with an adjoint complement to the Volume-of-Fluid (VoF) method for immiscible two-phase flows, e.g. air and water, which is widely used in marine engineering due to its computational efficiency. The particular challenge of the primal and the corresponding adjoint VoF-approach refers to the sharp interface treatment featuring ...

Experimental Validation of Volume of Fluid Method for a Sluice Gate Flow [PDF]
Advances in Mechanical Engineering, 2012 Laboratory experiments are conducted for 2D turbulent free surface flow which interacts with a vertical sluice gate. The velocity field, on the centerline of the channel flow upstream of the gate is measured using the particle image velocimetry technique.

Parabolic interface reconstruction for 2D volume of fluid methods [PDF]
Journal of Computational Physics, 2021 For capillary driven flow the interface curvature is essential in the modelling of surface tension via the imposition of the Young--Laplace jump condition. We show that traditional geometric volume of fluid (VOF) methods, that are based on a piecewise linear approximation of the interface, do not lead to an interface curvature which is convergent under

Unstructured un-split geometrical Volume-of-Fluid methods – A review [PDF]
Journal of Computational Physics, 2020 Geometrical Volume-of-Fluid (VoF) methods mainly support structured meshes, and only a small number of contributions in the scientific literature report results with unstructured meshes and three spatial dimensions. Unstructured meshes are traditionally used for handling geometrically complex solution domains that are prevalent when simulating problems

Free-Decay Heave Motion of a Spherical Buoy
Fluids, 2022 We examined the heave motion of a spherical buoy during a free-decay drop test. A comprehensive approach was adopted to study the oscillations of the buoy involving experimental measurements and complementary numerical simulations.

Assessment of Numerical Methods for Plunging Breaking Wave Predictions
Journal of Marine Science and Engineering, 2021 This study evaluates the capability of Navier–Stokes solvers in predicting forward and backward plunging breaking, including assessment of the effect of grid resolution, turbulence model, and VoF, CLSVoF interface models on predictions. For this purpose,
