Statistical models for the dynamics of heavy particles in turbulence

J Bec, K Gustavsson, B Mehlig - Annual Review of Fluid …, 2024 - annualreviews.org
When very small particles are suspended in a fluid in motion, they tend to follow the flow.
How such tracer particles are mixed, transported, and dispersed by turbulent flow has been …

Experimental study of inertial particles clustering and settling in homogeneous turbulence

AJ Petersen, L Baker, F Coletti - Journal of Fluid Mechanics, 2019 - cambridge.org
We study experimentally the spatial distribution, settling and interaction of sub-Kolmogorov
