Coupling functions:universal insights into dynamical interaction mechanisms
TL;DR: A comprehensive review of the analysis, understanding and applications of coupling functions can be found in this paper, where a variety of methods have been developed for detecting and reconstructing coupling functions from measured data.
Journal ArticleDOI
A functional subgrid drift velocity model for filtered drag prediction in dense fluidized bed
Jean-François Parmentier,Jean-François Parmentier,Olivier Simonin,Olivier Simonin,Olivier Delsart +4 more
TL;DR: In this paper, the effect of small unresolved scales on the large resolved scales computed with coarse meshes was investigated using a fully-resolved simulation, and the authors highlight the need to account for a subgrid drift velocity to obtain the correct bed expansion when using coarse meshes.

Some thermal hydraulic challenges in sodium cooled fast reactors
TL;DR: In this article, the main thermal hydraulic challenges in sodium cooled fast reactors, on the basis of the past experience, are summarized and compared using numerical and experimental tools used in the French Atomic Energy Commission (CEA).
Journal ArticleDOI
Implementation of an iterative solution procedure for multi-fluid gas–particle flow models on unstructured grids
TL;DR: Improved interpolation practices have been adopted to ensure the smoothness of the solution in situations where the phase effective density presents steep gradients, aiming at reproducing the discretisation typical of the staggered grid arrangement.
Journal ArticleDOI
CATHARE-3: A new system code for thermal-hydraulics in the context of the NEPTUNE project
TL;DR: The CATHARE-3 as discussed by the authors is the current industrial version of the CATHERARE-2 code, which is used for nuclear power plant safety analysis, in simulators and in coupled simulation tools.

Thermo-Fluid Dynamics of Two-Phase Flow
Mamoru Ishii,Takashi Hibiki +1 more
TL;DR: In this article, two-phase field equations based on time average are proposed. But they do not consider the effect of structural materials in a control volume on the two-fluid model.

A two-phase mixture theory for the deflagration-to-detonation transition (ddt) in reactive granular materials
Melvin R. Baer,J.W. Nunziato +1 more
TL;DR: In this article, a two-phase mixture theory is presented which describes the deflagration-to-detonation transition (DDT) in reactive granular materials, based on the continuum theory of mixtures formulated to include the compressibility of all phases and the compaction behavior of the granular material.
