Vibration-induced densification of granule materials
… pellets, there is a substantial increase in solids fraction due to the effects of particle shape and surface friction. Computer simulations applying the discrete element method are then used to investigate the influence of material properties, container geometry and vibration amplitude and …

HYDRODYNAMIC CHARACTERISTICS AND COAL COMBUSTION MODELING OF A HIGH VELOCITY FLUIDIZED BED (SOLIDS FRICTION FACTOR, TWO PHASE FLOW, PRESSURE PROFILE, FAST)
… limestone, and gypsum particles. The latter two solids are chosen because of their presence in the coal combustion process for sulfur removal. Data have been collected to study the effect of particle size, particle density, air flux, and solid flux on fluidizing characteristics of the three …

Density relaxation of granular matter through Monte Carlo and granular dynamics simulations
… with the handling and processing of bulk solids including pharmaceuticals, chemicals, agricultural and mining materials. Despite the enormous importance of these materials in society, their behavior is not well-understood; in fact, there is no known model available that is capable of …

Stochastic and deterministic dynamics investigation of the microstructure of granular materials
… tap intensity which produces a maximum bulk solids fraction. A key result that is found in this thesis is the mechanism responsible for the relaxation phenomenon is an evolving ordered packing structure propagating upwards from the plane floor.

Investigating multi-directional inhomogeneous granular suspensions
… after 15 min tracking time, however the solids fraction still shows under sampled regions after tracking for 3 h. Several techniques were used to investigate this, including as Poincaré maps and the global mixing index. A variation on the averaging technique is shown to account for under …

Improving settleability and achieving biological phosphorus removal through the application of sidestream gravimetric selectors
… in wastewater treatment to select for heavier solids, and has been used before in multiple small-scale systems. This is the first implementation of hydrocyclones in a full-scale plant for the purpose of increased settleability, while also achieving enhanced biological phosphorus removal without …
