Using what has become a celebrated catchphrase, Philip W. Anderson once wrote that
“more is different”(Science, Vol. 177, Issue 4047, pp. 393–396, 1972). First formulated in the …

Hydraulic erosion technology (HET) is a method of injecting a large amount of water into a
blocked fracture to enhance its permeability. However, the incipient motion characteristics of …

Spot fires created by wind–carrying firebrands are common in wildland–urban interface
(WUI) fires. Firebrand deposition over cubic blocks in tandem and parallel arrangements …

Pickup velocity, defined as the airflow velocity requirement of the initial movement of solid
particles, is the well-recognized minimum conveying velocity required of a pneumatic …

We study the incipient motion of single spheres in steady shear flow on regular substrates at
low particle Reynolds numbers. The substrate consists of a monolayer of regularly arranged …

The pickup characteristics of lump non-spherical particles in an oscillating airflow were
numerically studied on the basis of experimental verification. Five typical shapes of lump …

To reduce the airflow velocity and improve the pneumatic conveying performance of lump
coal particle, the pickup process and pickup prediction of lump coal particles with 5–15 mm …

Efficient transport of sand or cuttings is very important in the oil and gas industry, and the
fluid velocity in these processes should be sufficiently high to keep particles continuously …

Particle resuspension in a fully developed turbulent square duct flow is simulated using one-
way coupled large eddy simulation coupled with a Lagrangian particle tracking technique for …

Among the different regimes in multiphase pipelines, stratified flow is most prone to sand
deposition, owing to the low liquid velocity and the lack of mixing. The main goal of this study …
