摘要：
In the present work we investigate the problem of pattern formation by fluid now and mass transport in a viscous binary fluid mixture under osmosedimentation. We perform a numerical investigation of these patterns using spatial computational operators (R-2 --> R), computed from the spatial mass distribution field over time. Our main goal is to determine different dynamical regimes through analysis of the complex patterns arising from the osmosedimentation process. The results show that the pattern formation dynamics in the osmosedimentation process can be well characterized by means of these computational operators. (C) 2000 Elsevier Science B.V.
