Department of Physics, Moscow State University, Moscow 117234, Russia(February 8, 2008)We suggested a theory of clustering of inertial particlesadvected by a turbulent velocity field caused by an instabilityof their spatial distribution. The reason of the clustering in-stability is a combined effect of the particle inertia and finitecorrelation time of the velocity field. The crucial parame-ter for the instability is a size of the particles. The criticalsize is estimated for a strong clustering…

Oscillating grids turbulence generator for turbulent transport studies

An oscillating grids turbulence generator was constructed for studies of two new effects associated with turbulent transport of particles, turbulent thermal diffusion and clustering instability.
