摘要：

We report on experiments with small particles (tracers) in a ring vortex of thermocapillary flow (TF) in NaNO3 melt which form for favorable conditions "clouds" if TF is oscillatory and ring structures if TF is time-independent or time-independent with small disturbances. We call this novel phenomenon particle accumulation structure (PAS). PAS is in our case a three-dimensional phenomenon, but we express the hope that modelling PAS numerically can lead to the experimentally tested basis for modelling cloud formation in proto-planetary accretion disks, where these clouds could become embryos for planets, (C) 1999 COSPAR.
