Numerical Study on an Interface Compression Method for the Volume of Fluid Approach
Fluids, 2021 Many thermohydraulic issues about the safety of light water reactors are related to complicated two-phase flow phenomena. In these phenomena, computational fluid dynamics (CFD) analysis using the volume of fluid (VOF) method causes numerical diffusion ...

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.

Coupling non-local rheology and volume of fluid (VOF) method: a finite volume method (FVM) implementation [PDF]
EPJ Web of Conferences, 2021 Additional to a behavior switching between solid-like and liquid-like, dense granular flows also present propagating grain size-dependent effects also called non-local effects. Such behaviors cannot be efficiently modeled by standard rheologies such as µ(

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

Adjoint complement to the volume-of-fluid method for immiscible flows [PDF]
Journal of Computational Physics, 2021 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 ...

Improvement of a Simple Coupled VOF with LS (S-CLSVOF) Method
Journal of Chemical Engineering of Japan, 2023 In this study, an efficient conversion algorithm of level set function [Formula: see text] from volume fraction [Formula: see text] is developed. This method makes the calculation of [Formula: see text] easier than the conventional CLSVOF method, and the
