A coupled volume-of-fluid/level-set method for simulation of two-phase flows in unstructured meshes
(Elsevier, 2016-01)
Article.
Accés obert
Article.
Accés obert
This paper presents a methodology for simulation of two-phase flows with surface tension in the framework of unstructured meshes, which combines volume-of-fluid with level-set methods. While the volume-of-fluid transport ...

A packed-bed thermocline tank represents a proved cheaper thermal energy storage for concentrated solar power plants compared with the commonly-built two-tank system. However, its implementation has been stopped mainly due ...
A level-set model for thermocapillary motion of deformable fluid particles
(2016-12-01)
Article.
Accés obert
Article.
Accés obert
A new level-set model is proposed for simulating immiscible thermocapillary flows with variable fluid-property ratios at dynamically deformable interfaces. The Navier–Stokes equations coupled with the energy conservation ...
Direct numerical simulation of multiphase flows with unstable interfaces
(Institute of Physics (IOP), 2016-09-01)
Article.
Accés obert
Article.
Accés obert
This paper presents a numerical model that intends to simulate efficiently the surface instability that arise in multiphase flows, typically liquid-gas, both for laminar or turbulent regimes. The model is developed on the ...

The drain water heat recovery (DWHR) system is an interesting household technology to reduce energy costs and environmental impact. The objective of the utilisation of these devices is the recovery of the waste heat from ...
A level-set aided single-phase model for the numerical simulation of free-surface flow on unstructured meshes
(Elsevier, 2016-11-25)
Article.
Accés obert
Article.
Accés obert
A new single-phase scheme for the numerical simulation of free-surface problems on 3-D unstructured meshes is presented. The flow field is obtained from the discrete solution of the incompressible Navier-Stokes equations, ...
