Computational fluid dynamics for dense gas-solid fluidized beds: a multi-scale modeling strategy [PDF]

, 2004
Dense gas–particle flows are encountered in a variety of industrially important processes for large scale production of fuels, fertilizers and base chemicals.

Multi-scale Multi-attention Network for Moiré Document Image Binarization

, 2021
In this paper, we propose a Multi-scale Multi-attention Network (MsMa-Net) to binarize document images contaminated by moiré patterns from camera-captured screens.

Effect of cohesion on local compaction and granulation of sheared soft granular materials

EPJ Web of Conferences, 2017
This paper results from an ongoing investigation of the effect of cohesion on the compaction of sheared soft wet granular materials. We compare dry non-cohesive and wet moderately-to-strongly cohesive soft almost frictionless granular materials and ...

Concurrent multi-scale modeling of granular materials: Role of coarse-graining in FEM-DEM coupling [PDF]

, 2023
The finite element method (FEM) is commonly used for modeling continuum media, while particle simulation methods like the so-called discrete element method (DEM) are used for discrete systems.

Detrainment in deep convection

Geophysical Research Letters, 2012
This study explores the mechanisms that determine detrainment in deep cumulus convection. A set of 90 high‐resolution Large Eddy Simulations is used to systematically explore the sensitivity of continental deep convection to the relative humidity and ...

Optimized geothermal energy extraction from hot dry rocks using a horizontal well with different exploitation schemes

Geothermal Energy, 2023
In the foreseeable future, the geothermal exploitation from hot dry rocks (HDR) using a horizontal well will bear potential. Thus, in-depth studies should be conducted on the selection of injection-production scheme (IPS) and working fluid, design of ...

Multi-scale modeling of dispersed gas-liquid two-phase flow [PDF]

, 2004
In this work the concept of multi-scale modeling is demonstrated. The idea of this approach is to use different levels of modeling, each developed to study phenomena at a certain length scale.
