Generalized sweep-stick mechanism of inertial-particle clustering in turbulence

S Oka, S Goto - Physical Review Fluids, 2021 - APS
Inertial particles, ie, small heavy particles, can inhomogeneously distribute and form clusters
even in statistically homogeneous turbulence. When the Reynolds number of turbulence is …

Mechanisms for the clustering of inertial particles in the inertial range of isotropic turbulence
