International Journal of Coal Preparation and Utilization, 2018
In general, the washing of coal is greatly influenced by the amount of near-gravity material (NGM) present at the desired cut density. It is observed that the presence of a high percentage of NGM coal results in significant misplacement of particles to ...

Discrete phase model of domain walls in ferroelectric crystals
SPIE Proceedings, 2011A discrete phase model is used to simulate evolution of domain structures in ferroelectric materials. The discrete phase model balances the structural energy against local mechanical and electrical energies. Devonshire theory is used to model the structural energy while a finite element framework using scalar potential theory computes the local ...

Discrete Phase-Space Model for Quantum Mechanics
1989A quantum dynamical system is modeled by associating a complete set of orthogonal eigenfunctions labeled by position q (“pixels”), defined only at lattice points, plus other labelling indices (“colors”), and a complete set of orthogonal eigenfunctions labelled by momentum p, defined only inside the Brillouin zone, plus other corresponding labelling ...

Modelling coal gasification with CFD and discrete phase method
Journal of the Energy Institute, 2006In the present paper the authors describe a computational fluid dynamics model of a two-stage, oxygen blown, entrained flow, coal slurry gasifier for use in advanced power plant simulations. The discrete phase method is used to simulate the coal slurry flow.

Discrete Model of Fracture in Disordered Two-Phase Materials
1995Improved characterization of present-day composites that are manufactured to obtain optimal property values by microstructure effects necessitates a more thorough knowledge of the microstructural features and their cooperative interaction which determine the physical characteristics of the material.

DISCRETE MODEL REFERENCE ADAPTIVE CONTROL OF NON‐MINIMUM PHASE SYSTEMS
Optimal Control Applications and Methods, 1982SUMMARYA new approach of model reference adaptive control for non‐minimum phase systems is considered. The proposed adaptive controller ensures the stability of the closed‐loop system under a condition little restrictive in practice.

A discrete phase hybrid continuum-atomistic model for electrokinetics in nanofluidics
The Physics of Fluids, 2018The ever-growing field of micro- and nanotechnology has a great deal of interest in simulating dynamic phenomena of multiscale systems. Hybrid approaches that produce a trade-off between accuracy and computational costs play a key role in this area.
