Solids mixing and segregation in a gas spout-fluid bed-effect of the distributor design
This work is concerned with the assessment of a newer version of the spout-fluid bed where the gas is supplied from a common plenum and the distributor controls the operational phenomenon. Thus the main body of the work deals with the effect of the distributor design on the mixing and segregation …

Heat transfer between a shallow fluidized bed and a single horizontal tube immersed in the bed
The heat transfer coefficient between a horizontal tube and a shallow fluidized bed of alumina particles (335-1261 micron) was measured, and the effects of the tube elevation (10-40 mm), static bed height (10-40 mm), and the design of the distributor were investigated. The cloud zone effect i.e. a …

An evaluation of the entrance requirements at Radford College
The heat transfer coefficient between a horizontal tube and a shallow fluidized bed of alumina particles (335-1261 micron) was measured, and the effects of the tube elevation (10-40 mm), static bed height (10-40 mm), and the design of the distributor were investigated. The cloud zone effect i.e. a …

Searching for the developmental origins of fairness
… addressed two major questions related to the development of infants’ concern for fairness: 1) at what age do infants first show a concern for fairness in terms of how objects should be distributed? and 2) how does group membership influence infants’ expectations about how objects should be …

Computer solution of equations for three centrifugal distributor configurations
Centrifugal distributors are used extensively for the broadcast application of granular materials such as seed, granular fertilizer, and agricultural chemicals. A major problem with this equipment is nonuniform spreading which frequently results in reduced crop yield. The object of this study is to …

THE VEHICLE ROUTING PROBLEM WITH DEMAND RANGES
The classic Capacitated Vehicle Routing Problem (CVRP) has been studied in the Operations Research field for over 5 decades. This thesis formulates the vehicle routing problem with a variation that has not been studied in detail. It is called the Vehicle Routing Problem with Demand Ranges (VRPDR). …

Effect of conical distributors on evaporator and system performance
This thesis presents the results of the study to experimentally examine effects of the distribution of refrigerant and air in the evaporator using a conical distributor on system COP and capacity. Several conditions at the distributor inlet are varied including quality, mass flux, and orientation …

Fluidization and soot filtration in a rotating fluidized bed
… fluidized bed (RFB) has been investigated for the removal of soot from diesel engine exhaust. This requires necessitating an understanding of the nature of fluidization, particle mixing and filtration in the RFB. In an RFB, particles are subject to a centrifugal force which can be much larger …

A bacteriological survey of the practices used by a local creamery in handling and manufacturing dairy products
… designed to prevent a product being delivered to the consumer in an unsanitary condition. Large numbers of bacteria do not necessarily condemn food products, but usually an excessive number of bacteria is associated with inferior materials and unsanitary practices. Definite legal limits of the …

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 …

Some Aspects of the Performance of Rotating Fluidized Beds
A Survey of the literature showed that little has been published on how to design a rotating fluidized bed combustor and that most work had concentrated on fluidization conditions. This thesis describes investigations into the design, construction and operation of rotating fluidized bed combustors. …
