This review is motivated by the fast progress in our understanding of the physics of particle-
laden turbulence in the last decade, partly due to the tremendous advances of measurement …

A critical analysis of turbulence modulation in particulate flow systems: a review of the experimental studies

MM Hoque, JB Joshi, GM Evans… - Reviews in Chemical …, 2024 - degruyter.com
In multiphase particulate systems, the turbulence of the continuous phase (gas or liquid) is
modulated due to interactions between the continuous phase and the suspended particles …

How electrostatic forces affect particle behaviour in turbulent channel flows

H Zhang, Y Cui, X Zheng - Journal of Fluid Mechanics, 2023 - cambridge.org
