From Discrete Particle Model to a Continuous Model of Geldart A Particles

Chemical Engineering Research and Design, 2005
A reliable description of dense gas - solid two-phase flows of Geldart A particles in gas-fluidized beds at life-size scale is of great practical importance in process industries. The classical two-fluid model, based on the kinetic theory of granular flows (KTGF), provides a very promising theoretical framework for predicting large-scale gas-solid two ...

The particle-phonon model and particle-core model for 63Cu

Nuclear Physics A, 1973
Abstract The accuracy of the particle-phonon and particle-core models in describing the properties of 63 Cu is studied. From the measured properties of the low-lying levels, adopted values and uncertainties are deduced, which are used to obtain the model parameters by fitting procedures.

Modelling Particle Fluxes

1993
Marine particles play an important rôle in the chemistry of the oceans, not only because they provide sources of, and sinks for, solutes, but also, and especially, because they move relative to water. Examples of the resulting fluxes can be seen in the vertical transport of organic carbon and nitrogen, calcium carbonate, or trace metals. The components

Model particles as representatives of particles in nature

Netherlands Journal of Aquatic Ecology, 1994
Small particles and organisms in the aquatic environment can be represented in model simulations in a very direct way by ‘model particles’. The behaviour of one model particle is a close approximation of that of a real particle; a set of model particles corresponds to a random sample of the corresponding set of real particles. A description is given of
