Abstract
We report the effect of interstitial fluid on the extent of segregation by imaging the pile that results after bidisperse color-coded particles are poured into a silo. Segregation is sharply reduced and preferential clumping of small particles is observed when a small volume fraction of fluid Vf is added. We find that viscous forces in addition to capillary forces have an important effect on the extent of segregation s and the angle of repose ν. We show that the sharp initial change and the subsequent saturation in s and ν occurs over similar Vf. We also find that a transition back to segregation can occur when the particles are completely immersed in a fluid at low viscosities. © 2000 The American Physical Society.
