SINOPSIS

To investigate the two-way interaction between particles and fluid turbulence, a homogeneous flow field including solid particles was numerically simulated. Particular attention was focused on the clustering of particles, which might enhance turbulence, by energy supply through larger scale in comparison with dispersed particles. In the particle Reynolds number range from 50 to 400, it was found that particle clusters are formed by wake and vortex shedding enhances them. The Reynolds number dependence, dynamics and time scale of particle clusters are discussed in this paper.
