A study of the cane sugar diffusion process.
A mathematical model has been developed to represent the extraction of sugar from sugar cane in the diffusion process. As a consequence of the structure of prepared cane, extraction is postulated to occur via two first ...
Kinetic and mechanistic studies on the biological and chemical leaching of nickel from sulphide ores.
The aim of this investigation was to extend the knowledge of the bacterial leaching of copper and zinc sulphides into the area of nickel sulphide leaching. By far the major portion of both theoretical and practical expertise ...

The lightning ground flash : an engineering study.
The thesis is concerned with a study of the electrical engineering parameters of the lightning ground flash - i.e. the statistical distributions of peak current amplitudes, discharge current waveform characteristics, and ...
An investigation into the Fischer-Tropsch synthesis over supported ruthenium in a stirred gas-solid reactor.
A stirred gas-solid reactor has been used to study the Fischer-Tropsch synthesis over a supported ruthenium catalyst. Detailed catalyst characterisations were conducted on both fresh and used catalyst samples and included ...
An investigation of a supersonic chemical reactor.
The development of a supersonic chemical reactor is examined. The central concept of such a reactor is that gases can be expanded to supersonic speed which will result in a decrease in their static temperature to the ...
A study of the use of statistical turbulence parameters in correlating axial dispersion data in the central core of air flowing in a pipe.
The longitudinal fluctuations at a point in the core of air flowing through a 15 cm. diameter pipe at a mean centerline velocity of 13.4 and 29.5 m/sec. were measured with a hot-wire anemometer. This signal, after analog ...
Dispersion in slowly moving fluids.
This work is concerned with the characterization of slowly moving fluids and was carried out on the flow of water through a narrow sedimentation tank. Dispersion in the type of flow structure involved is caused mainly by ...
