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…
