Liquid Nanodroplets Spreading on Chemically Patterned Surfaces
Gary S. Grest, David R. Heine, Edmund B. Webb
Controlling the spatial distribution of liquid droplets on surfaces via surface energy patterning can be used to control material delivery to specified regions via selective liquid…
Plug flow and the breakdown of Bagnold scaling in cohesive granular flows
Robert Brewster, Gary S. Grest, James W. Landry +1
Cohesive granular media flowing down an inclined plane are studied by discrete element simulations. Previous work on cohesionless granular media demonstrated that within the steady…
Three-dimensional shear in granular flow
Xiang Cheng, Jeremy B. Lechman, Antonio F. Barbero +5
The evolution of granular shear flow is investigated as a function of height in a split-bottom Couette cell. Using particle tracking, magnetic-resonance imaging, and large-scale si…
Jamming in granular hopper flow
James W. Landry, Gary S. Grest
Large-scale three dimensional molecular dynamics simulations of hopper flow are presented. The flow rate of the system is controlled by the width of the aperture at the bottom. As…
Diverse Spreading Behavior of Binary Polymer Nanodroplets
David R. Heine, Gary S. Grest, Edmund B. Webb
Molecular dynamics simulations are used to study the spreading of binary polymer nanodroplets in a cylindrical geometry. The polymers, described by the bead-spring model, spread on…
