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 ...

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

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

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 ...

A numerical framework for simulating fluid-structure interaction phenomena [PDF]
Fracture and Structural Integrity, 2014 In this paper, a numerical tool able to solve fluid-structure interaction problems is proposed. The lattice Boltzmann method is used to compute fluid dynamics, while the corotational finite element formulation together with the Time Discontinuous ...

Methods for warming intravenous fluid in small volumes [PDF]
Canadian Journal of Anaesthesia, 1998 Laboratory experiments were performed to determine warming rates of albumin 5% at room temperature and human packed red blood cells (PRBCs) at 4 degrees C in small volumes. Four methods used in clinical practice to warm volumes appropriate for neonates were studied.The fluids were warmed either by infusion through a fluid warmer with temperature ...

A volume of fluid method for simulating fluid/fluid interfaces in contact with solid boundaries [PDF]
Journal of Computational Physics, 2015 In this paper, we present a novel approach to model the fluid/solid interaction forces in a direct solver of the Navier-Stokes equations based on the volume of fluid interface tracking method. The key ingredient of the model is the explicit inclusion of the fluid/solid interaction forces into the governing equations. We show that the interaction forces
