Rheophysical Investigation in Concentrated Particle Suspensions

Avalanches of Concentrated Granular Suspensions Down an Inclined Plane

“…Comparing our results and the rheometrical data produced by Wiederseiner [3] with the same model suspensions should help understand the complex dynamics of highly concentrated suspensions.…”

“…Two flow geometries are studied: a viscometric flow in a Couette cell (coaxialcylinder geometry) and a dambreak flow (time-dependent flow induced by the coUapse of a fixed volume of fluid down a flume). Rheometrical experiments are presented in Wiederseiner's paper [3], while dam-break experiments are outhned here.…”

Note: Eliminating stripe artifacts in light-sheet fluorescence imaging

“…For living biological samples ranging from embryonic development studies all the way to neuroscience, it provides high resolution, contrast, specificity, penetration depth, and image acquisition speed, and has relatively low levels of phototoxicity and photobleaching [1][2][3][4][5] . For colloidal and granular materials, it allows particles to be tracked for study of soil mechanics 6,7 , flow behavior and rheology [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] , packing and jamming phenomena 7,21,22,24,25 . For all such applications, a sample is illuminated by a laser sheet, resulting in a two dimensional cross-sectional image, which can be combined into a stack of scanned images to obtain a threedimensional representation 26,27 .…”
