DOI: 10.1016/j.apt.2019.03.006
Abstract: Abstract Triboelectric separation is an effective way to separate fine powders with particle sizes and densities in the same order of magnitude. Many relevant process variables influence the charging behaviour; however, the corresponding effects on… read more here.

DOI: 10.1016/j.ijmultiphaseflow.2017.01.011
Abstract: Abstract Entrained-flow slagging coal gasifiers display large conversion efficiencies and small levels of unconverted carbon at the exhaust. Both features are apparently at odds with the fairly small “space-time” of the particle-laden gas feeding, as… read more here.

DOI: 10.1080/02786826.2020.1757032
Abstract: Abstract We investigate the effect of primary ion diffusion charging on particle wall loss in Teflon smog chamber experiments. Primary ion losses are balanced between wall deposition and diffusion charging to larger particles; further, the… read more here.

DOI: 10.1088/1361-6595/ac1715
Abstract: The effects of heavy particle-wall interaction on a cylindrical plasma source discharge are investigated, through hybrid particle-in-cell/fluid simulations. The bulk plasma is considered quasineutral with isothermal electrons, and with no secondary electron emission from the… read more here.
