TL;DR: A cellwise conservative unsplit (CCU) advection scheme for the volume of fluid method (VOF) in 2D with high order accuracy and potential improvements of the VOF method with the use of more precise interface representation techniques and the future extension of the CCU scheme to 3D are discussed.

TL;DR: In this paper, a compressible model is proposed to simulate the physical behavior of a free surface between two fluids, which is composed of four equations in two space dimensions: two for each fluid mass conservation, and two for momemtum conservation.
Abstract: In order to simulate numerically the physical behaviour of a free surface between two fluids, we have developped a compressible model, able to correctly reproduce sloshing at high Bond number (capillary forces neglectible). We will first present the model. It is composed of four equations in two space dimensions : two for each fluid mass conservation, and two for momemtum conservation. The gas and liquid phases are supposed to be compressible fluids following an isothermal linearized equation of state. A mechanical equilibrium relation closes the model (the equilibrium model). Relaxing this relation, we obtain a new model (the relaxation model) that is more adapted for numerical treatment. The second part of the paper is dedicated to the presentation of the numerical method that we used. We explain why it does not need a scheme for the volume fraction. In particular, there is no specific algorithm to localize the interface, as in VOF, Level-Set or Front Tracking methods. The last part of the paper is devoted to some validation results, compared to analytical solution or experimental data.Copyright © 2002 by ASME

TL;DR: In this article, a finite-volume method adapted to a structured or unstructured mesh is used to solve the Navier-Stokes equations and the free surface is simulated by the "volume-of-fluid" interface capturing method.
Abstract: We present the results of simulations obtained with a free-surface flow solver based on the following method. The free surface is simulated by the “volume-of-fluid” interface capturing method. This code solves the Navier–Stokes equations using a finite-volume method adapted to a structured or unstructured mesh. The system is constructed using a fully coupled approach. This global approach allows the simulation of complex flow as a breaking or merging wave. Moreover, with the use of a 2D+T decomposition, it is possible to simulate three-dimensional steady flow.

TL;DR: In this paper, a 2D model of the fluid flow and coupled heat transfer between the working fluid and the solid refrigerant (gadolinium) is proposed to evaluate the thermal behavior of a magnetic-Brayton-based parallel plate reciprocating active magnetic regenerator (AMR).
Abstract: This paper evaluates the thermal behavior of a magnetic-Brayton-based parallel plate reciprocating active magnetic regenerator (AMR). A time-dependent, 2D model of the fluid flow and the coupled heat transfer between the working fluid and the solid refrigerant (gadolinium) is proposed. A hybrid calculation method which consists of an analytical solution for the flow and a numerical solution for the thermal field has been adopted. Results for the cooling capacity as a function of the temperature span and mass flow rate agree well with trends observed in experimental data and other theoretical models available in the literature. The volume of fluid displaced through the channels during the isofield processes influences significantly the AMR performance. For a cycle frequency of 1 Hz, the cycle-averaged cooling capacity reaches a maximum when the utilization factor is 0.1 and the displaced fluid volume equals 62% of the fluid volume of the AMR.
