Heat and mass gas-to-solid coefficients associated with the vaporisation of water and some hydrocarbons from the surface of a porous, monolithic structure were experimentally established.
Experiments in a cold model have been conducted to determine lateral solid diffusion coefficients in a narrow fluidised bed.
To understand the phenomena, two types of hydrodynamics models that compute turbulent and bubbling behavior were used to estimate radial and axial gas and solid dispersion coefficients.
By the CITT, the Li+ solid diffusion coefficients within LiMn2O4 have been determined at different voltages and different galvano-charge currents.
For the higher order element discretization method, the special concerns are given to the numerical calculations of the single-layer potential, the double layer potential and the solid angle coefficients.
It is concluded that, although a simple correlation for the solid dispersion coefficients compiled in this work is useful, the CCBM model is a much more reliable idealisation in describing and scaling up axial solid mixing in fluidised beds.
The solid diffusion coefficients obtained have been used to solve a heat transfer problem and discuss the feasibility of a fluidised bed system that makes use of narrow fluidised beds arranged to transfer heat from bed to bed through a separating wall between them.
Data from a 100 tonne per hour raw sugar dryer is reconciled against the dynamic solids transport model, by estimating overall solids transport coefficients.
This study presents a comparison of the computed axial solids dispersion coefficients for cork particles to the NETL riser cork data.
The turbulence properties, the Reynolds stresses, the granular temperature spectra and the radial and axial gas and solids dispersion coefficients are computed.
The capacity intermittent titration technique (CITT) has been developed on basis of the ratio of the potentio-charge capacity to the galvano-charge capacity (RPG) method to determine continuously the solid diffusion coefficient D of the intercalary species within insertion-host materials.
