The main purpose of this article is to investigate the effects of the subgrid fluid turbulence on
the motion of nonsettling colliding particles suspended in steady homogeneous isotropic
turbulent flow. An additional goal is to characterize the statistical properties of the subgrid
fluid turbulence “viewed” by inertial particles to support the development of large eddy
simulation (LES) approach for particle-laden turbulent flows. Two types of numerical
experiments have been carried out: first, the discrete particle trajectories were computed …
