A study of the transport of solids in hospital above ground drainage systems
The transport of solids in "horizontal" above ground drainage pipes was the subject of an investigation aimed at establishing a method for the design of deposit free drainage systems. Tests were based on the measurement of solid velocity in a discharge pipe of variable gradient, the solid being a …

Numerical Simulations of Thermo-Fluid Phenomena in Microwave Heated Packed and Fluidized Beds
… modeled with multiphase flow equations.The gas velocity profiles along with the solid and gas temperature profiles for packed and fluidized beds are provided. F or the fluidized beds, the hydrodynamics is modeled using FLUENT and the solid velocity profiles are also determined.

The measurement of the velocities of particles in an air-solid flow
… experimental work on two-phase flows. Particle velocity is an especially important property, but most available techniques either disturb the flow or are slow or inaccurate. The laser-Doppler velocity meter, LDV, was developed for measurements in single-phase flows, but it has been demonstrated …

Correlation of laboratory and installed drainage system solid transport measurements
The transport of solids in 'horizontal' above ground drainage pipes was the subject of an investigation, based upon the measurement of both sterile 'model' solid velocity and 'live' waste load velocity, aimed at the establishment of a sound basis for the development of a comprehensive empirical …

Characterization of gas-solid two-phase flow by using electrical capacitance tomography
… the boiler system and the non-uniformity of its velocity, which leads to a decrease in the production of energy and higher emission of carbon dioxide. To achieve these aims, three objectives are set: (i) determination of the optimum conditions for an AC-ECT system to measure the capacitance of …

Splitting solution scheme for material point method
… used for modelling large deformations of solid mechanics problems. Due to the particle based spatial discretiza- tion, MPM is naturally capable of handling large mass movements together with topological changes. Further, the Lagrangian particles in MPM allow an easy implementation of …

Heterogeneous flow structure and gas-solid transport of riser
… aims to understand physical mechanisms of gas-solid transport and riser flow, investigate heterogeneous flow structures of gas-solid transport and their formation mechanism of the in riser flows, both in axial and radial directions. It provides sound interpretation for the experimental …

MPM study of water wave interaction with porous seawalls
… conditions. MPM has been widely used to solve solid mechanics problems with history-dependent variables, but the application of this method to fluid mechanics has been rare. In MPM, the background mesh is only used to solve the governing equations. The material properties are stored at the …

Investigation of fluidized bed systems using coupled DEM-CFD framework
… comparable to the particle diameter of the solid phase. The novelty of this work lies in the development and validation of a two-grid formulation that removes the resolution restrictions of the conventional DEM-CFD framework. The results obtained from this new framework agree reasonably well …
