Journal ArticleDOI
Direct numerical simulation of triboelectric charging in particle-laden turbulent channel flows
TL;DR: In this article, the charging process of particles dispersed in a turbulent channel flow at a friction Reynolds number of 2 was investigated. But the authors focused on the analysis of the interplay between the different physical mechanisms underlying particle electrification, such as fluid turbulence, particle dynamics and particle collisions.
Journal ArticleDOI
Large eddy simulation of triboelectric charging in pneumatic powder transport
TL;DR: In this article, large eddy simulations are performed to simulate the turbulent flow of the gaseous phase while the particulate phase is described in Lagrangian framework, and a model describing the charge distribution in an insulating hose is also developed.
Journal ArticleDOI

TL;DR: In this paper, a combined experimental and numerical study of the evaporation and solid layer formation of single bi-component mannitol-water droplets in hot air is presented.
Journal ArticleDOI
Evaluation of the parameters influencing electrostatic charging of powder in a pipe flow
TL;DR: In this article, the charging process of powders during pneumatic transport was studied numerically by means of large eddy simulations and a range of design parameters was then analyzed statistically applying the Design of Experiments methodology.
Journal ArticleDOI
A model for the non-uniform contact charging of particles
TL;DR: In this paper, a non-uniform charge distribution on the particles surface during particle-wall and inter-particle collisions is considered and the results obtained with the new model are compared to data of single particle charging experiments.
