Sharing Beds
Sharing Beds, a collection of three interconnected novellas, follows young women navigating family and romantic relationships, missing sisters and mothers, sticking to routines, making new homes, adopting stray cats, reading books and trying to write. These characters feel most close to reality …

Gas Fired Fluidized Beds
… have been made of gas combustion in fluidized beds. A mathematical model has been developed which gives a qualitative estimation of the bed temperature profiles in the axial direction. The concept of Effective Thermal Conductivity is discussed, and bed conductivities are re-defined bearing in …

The performance of fluidized beds, packed beds, and screens as fuel cell electrodes
At present, most fuel cells employ porous gas diffusion (PGD) electrodes. Although much effort has been spent on their development, the performance and cost of PGD electrodes are still major obstacles to the successful commercialization of fuel cells. As a means to bypass the drawbacks associated …

Visualizing fluidized beds with X-rays
… stereography, and particle tracking to fluidized beds of glass beads, ground walnut shell, and ground corncob operating with a variety of flow conditions. 3-D local, time-averaged gas holdup is calculated from CT data, while dynamic features are captured by X-ray stereography. The results show …

Gas distribution in shallow packed beds
Packed beds have many industrial applications and are increasingly used in the process industries due to their low pressure drop. With the introduction of more efficient packings, novel packing materials (i.e. adsorbents) and new applications (i.e. flue gas desulphurisation); the aspect ratio …

Mass transfer in aerated vibrated beds
… transfer process is more important in shallow beds, where strong solid mixing occurs, than in deeper beds, where bulk-circulation patterns affect the naphthalene sublimation. Higher mass transfer rates are obtained with larger as well as heavier particles.

Eulerian-Eulerian Modeling of Fluidized Beds
… further illustrated by applying it to fluidized beds containing coal, switchgrass, poplar wood, and cornstover biomass particles and coal-biomass binary mixtures. The adjusted mass model was further analyzed for bed expansion heights of different mixtures, and for solids distribution by analyzing …

Kinetics of hydration of AlN powder beds
Includes bibliographical references (pages 228-230).

The behaviour of freely bubbling fluidized beds
Gas fluidized beds have provided fascinating and infuriating problems for both the academic and industrial engineer. Although fluidization phenomena have been the subject of many hundreds of papers we still cannot dispense with experimentation in order to predict bed behaviour even for relatively …

Combustion of Coal in Shallow Fluidised Beds
… heat transfer rate especially in very shallow beds. Experimental data on heat transfer in coalfired fluidized beds have been amassed and are in close agreement with theoretical predictions. The contribution of radiation to the total heat transfer has been determined through experiment and …

The flow behaviour of shallow fluidised beds
The flow behaviour of shallow gas-fluidised beds was studied. experimentally using a rotational viscometer, and an inclined open channel. Initially, tests were carried out with the viscometer in order to establish qualitative trends in the flow properties of a variety of materials over a wide range …

Coalescence of secondary dispersions in packed beds
… of the coalescence of secondary dispersions in beds of monosized glass ballotini. The variables investigated were superficial velocity, bed depth, ballotini size and dispersed phase concentration. Equipment was designed to generate a toluene ln water dispersion with phase ratios from 0.1 - 1.0 …

Coalescence of secondary dispersions in fibrous beds
SUMMARY A study has been made of the coalescence of secondary dispersions in a fibrous bed. The literature pertaining to the formation, hydrodynamic behaviour and methods of separation of droplets less than one hundred micrometres in diameter has been reviewed with particular reference to fibrous …

Sedimentology of the Cape Town boulder beds
Gravelly sediment layers in fossil beaches around the Cape Peninsula and False Bay in South Africa are assumed to be Pliocene in age and are essential for reconstructing the ancient sedimentary dynamics along the shoreline in the greater Cape Town region. The cobble- to boulder-size clasts in these …
