title = "Particle-turbulence interactions in Homogeneous and Isotropic Turbulence",
abstract = "The main motivation of this work is to study the particle-turbulence interations in Homogeneous Isotropic Turbulence (HIT). Several fully coupled DNS simulations of a 1283 periodic box with discrete particles are performed. Parameters like particle density and particle volume fraction are varied and the statistics obtained are compared with single-phase HIT. Our results show that dissipation (εf ) drops up to 11\% with increasing Stokes number (St) and up to 9\% when increasing particle volume fraction (αp). The statistical properties of the particles are analysed and compared to the well known Tchen-Hinze equation. The results show that the presence of particles signigicantly modifies the statistical properties of the turbulence, especially when the Stokes number increases.",
