Lubrication With Granular Flow: Continuum Theory, Particle Simulations, Comparison With Experiment
Studies of particle flows have followed three parallel paths: (1) experiment, (2) analysis based on the assumption of a continuum, and (3) direct particle simulation. In this paper, we perform continuum and particle analyses and compare them to each other, and to previously reported experiments. Both the particle simulations and the continuum model over-predict the experimental normal load and ...
متن کاملDiscrete Particle Simulation of Granular Flow
Granular materials, which can be either wet or dry and range from nanometers to centimetres in size, are widely encountered in industries and in nature. As with solids, they can withstand deformation and form heaps; as with liquids, they can flow; as with gases, they exhibit compressibility. These features give rise to another state of matter that is poorly understood (Ennis et al., 1994; Jaege...

15 صفحه اولMeasurements of particle dynamics in slow, dense granular Couette flow.
Experimental measurements of particle dynamics on the lower surface of a three-dimensional (3D) Couette cell containing monodisperse spheres are reported. The average radial density and velocity profiles are similar to those previously measured within the bulk and on the lower surface of the 3D cell filled with mustard seeds. Observations of the evolution of particle velocities over time reveal...
متن کاملLes of Gas-particle Turbulent Channel Flow (the Effect of Inter-particle Collision on Structure of Particle Distribution)
Particle dispersion in a fully-developed turbulent flow was studied. Numerical simulations with two-way coupling were performed for downward particle-laden turbulent flows in a vertical channel. Fluid turbulence was calculated by using LES, while the particle motion was treated by Lagrangean approach. In addition, inter-particle collision was taken into consideration. In this work, we focused o...
