摘要：

The motion of small suspended particles in the two-dimensional stationary vortex flow arising in the half-zone model of crystal growth is investigated. The particle dynamics is modeled by a modified Maxey-Riley equation assuming one-way coupling. The calculations for gravity as well as microgravity conditions are performed for configurations similar to the one used in the experiments. The computed trajectories and their analysis shed some light on the formation mechanism of the particle accumulation structures (PAS) which have been observed in half-zone experiments.
