The role of collective effects on settling velocity enhancement for inertial particles in turbulence

The role of collective effects on settling velocity enhancement for inertial particles in turbulence

A particle-laden homogeneous isotropic turbulent flow is studied experimentally to understand the role of collective effects (e.g. particle–particle aerodynamic interactions caused by local particle accumulation) on the settling velocity of inertial particles (Stokes number: $0.3
