Abstract
In recent years, one of important aspects of the granular material physician industries is controlling way of the granular flow. One of the best ways to do this is use of mechanical vibrations to guide the flow of particles in desirable way. This paper theoretically and experimentally investigates the effect of horizontal sinusoidal vibration on the particles flow. Certainly, the base vibration causes the spherical particles collide with each other and with the wall. These collisions cause their moving and displacement which is interpreted as flow. In this study, a new numerical model of spherical particles movement and the exerted forces from them to each other and also on the wall due to the vibration is proposed. Discrete Element Method (DEM) is used here. Finally, the presented numerical model is compared with experimental model and a good agreement between them is noticed.Index Terms—granular materials, mechanical vibrations, d...
