Pattern characterization: A case study in osmosedimentation

In the present work, we investigate the ability of recently proposed comput ational operators to characterize the problem of pattern formation by fluid flow and mass transport in a viscous binary fluid mixture under osmosedime ntation. We perform a numerical investigation of these patterns using three computational operators (R-2-->R), computed from the spatial mass distribu tion, the streamlines, and the velocity fields. Our main goal is to demonst rate the ability of these computational operators to distinguish different dynamical regimes in the complex patterns arising from the osmosedimentatio n process.
