In partially wet granular beds, liquid migrates between particles due to collisions and contacts. This, in turn, influences the flow behaviour of bed. We investigate redistribution moving monodisperse a rotating drum using Discrete Element Method (DEM) simulations. For weak capillary forces, re-distribution, induced by continuous particles, leads concentration core bed, where is quasi-static. H...

A micro-polarimeter with a 40 nL probe volume was configured so that it is compatible with capillary-scale flowing stream analysis. The optical configuration consists of two polarizing optics, a capillary, a laser source and a photodetector which is very simple to configure with low cost components. This unique polarimeter is based upon the interaction of a linearly polarized laser beam and a c...
