XPS relies on advanced contact models to accurately describe flow behavior of granular materials.

In preliminary engineering studies and equipment commissioning, readily available simulants with certain resemblances to the target waste, such as particle size, may be employed. However, for the validation of engineering processes, it is crucial to use simulants that closely replicate the physical and flow characteristics of the waste material, typically excluding radioactivity. The production of such simulants can entail significant costs. To facilitate the development of novel engineering sol...

The oil and gas industry, particularly in transportation and production, heavily relies on pipeline systems. It is an inevitable fact that petroleum products, such as oil and gas, extracted from wells always contain solid pollutants originating from various sources like dust, sand, and hydraulic fracturing operations. During operation, solid particles carried by the fluid flow continuously impact the pipeline walls, potentially leading to significant cumulative damage over time on the surfaces o...

This paper investigates the strength and critical state (CS) behaviours of granular materials via DEM simulations of true triaxial drained tests under three different loading modes including constant b (intermediate stress ratio) tests with constant σ1′ (major principal stress), constant p′ (mean pressure) and constant σ3′ (minor principal stress) respectively. To this end, a series of samples are generated with the same particle size distribution, and with the confining stresses ranging...

Railroad ballast exhibits distinct morphological characteristics represented by shape irregularity, corner angularity, and surface texture. Upon repeated train loading, the morphology of ballast undergoes inevitable degradation, particularly in terms of its corner sharpness, which can affect track performance and even pose a substantial threat to operational safety. These aspects have rarely been captured insightfully in most DEM studies on ballast. In contrast, this study examines the influence...

Bulk solids science has advanced significantly over the past half a century, yet there is much more to explore and develop.

The new design is applicable to a wide range of equipment across many industries.
