An Observational Study of Entrainment Rate in Deep Convection
This study estimates entrainment rate and investigates its relationships with cloud properties in 156 deep convective clouds based on in-situ aircraft observations during the TOGA-COARE (Tropical Ocean Global Atmosphere Coupled Ocean Atmosphere Response ...

Numerical investigation of air-entrainment in skimming flow over stepped spillways
As a widely used flood energy dissipator, the stepped spillway can significantly dissipate the kinetic or hydraulic energy due to the air-entrainment in skimming flow over the steps.

Numerical Simulation and Evaluation of Campbell Running and Gating Systems
The most common problems encountered in sand casting foundries are related to sand inclusions, air, and oxide films entrainment. These issues can be addressed to a good extent or eliminated by designing proper running systems.

Air Entrainment and Slope Erosion During Overflow on a Levee Covered by Non-Uniform Turfgrass
To mitigate flood damage caused by overflow from a levee, it is essential to prevent the levee failure or extend the time to breaching. Although turfgrass on a levee slope is effective in suppressing erosion, insufficient maintenance can reduce its ...

Air entrainment in hydraulic engineering [PDF]
Despite the relevance of 'white water' phenomena to hydraulic engineering, most progresses have been led by multiphase flow experts. In this paper the writer reviews the basic mechanisms of air entrainment : singular aeration and interfacial entrainment. He presents a ba-sic dimensional analysis and he discusses similitude and scale effects.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward
