Outline of Final Research Achievements

By developing a highly accurate and efficient parallel program for analyzing the motion of inertial particles in turbulent flows, we realized large-scale numerical experiments for tracking the particles in direct numeical simulations of turbulence. The relationships between vortex-cluster structures, which are unique to high Reynolds number turbulence, and the motion of inertial particles were investigated. As a result, we showed that particles with large inertia tend to concentrate on the outside of the vortex cluster. We also clarified the Reynolds number dependence of the behavior of particles with large inertia and provided reliable results on the role of turbulence in the planetesimal formation process in protoplanetary disks.
