The underground cemented backfilling of tailings slurry in metal mines is an important
guarantee for controlling goaf, reducing tailings storage, and ensuring mining safety. As a …

This first-of-its-kind review discusses the hydrodynamics for polyolefin productions in slurry
reactors using CFD. Past reviews in this field are specifically focused on the CFD …

During oil and gas well drilling, the filtration control of bentonite water-based drilling fluids
(BT-WBDFs), as an environmentally friendly fluid, is crucial to avoid formation damage and …

Hydrotransport of industrial powders and bulk materials such as minerals, mineral tailings,
coal, ash, and sand is regarded as an efficient means of transportation. Pipelines ranging in …

The rheological and filtration performance of drilling fluids greatly depends on the additives
used. To address the negative impact on the drilling fluid performance stemming from …

Inadequate hole-cleaning in an annulus leads to several problems such as mechanical pipe
sticking, premature bit wear, formation fracturing, and/or slow drilling. However, the literature …

This study analyses the impact of particle polydispersity using the Eulerian-Eulerian (EE)
and Lagrangian-Eulerian (LE) modelling approaches in the context of wellbore cleaning …

Accurate estimation of volume fraction and pressure gradient is considered indicating
parameters of efficient cuttings transportation. It is vital, in this regard, to consider all …

Cemented high-concentration backfill (CHB) is an indispensable solution for mitigating risks
associated with underground mining voids and surface tailings ponds. The accurate …

In this study, the potential of using a polyacrylamide-silica nanocomposite (PAM-S) to control
the filtration properties of bentonite water-based drilling muds under different salinity …
