This thesis is concerned with enhancing analysis tools for evaluating the non-linear dynamics of rotor bearing systems and in particular those where non-linearity is likely to result in aperiodic or chaotic behaviour, such as rolling element bearing systems. The tool to be enhanced was the transfer matrix approach which has been extensively used in the past for analysing linear rotor bearing systems. However, its use for evaluating non-linear behaviour has been virtually non-existent. Hence, the major aim of the thesis is to extend transfer matrix capabilities to handle non-linear systems. To this end a harmonic balance transfer matrix technique capable of analysing non-linear systems with multiple pedestal supported bearings was first developed. However, this approach is restricted to periodic response. To enable the analysis of non-linear systems with non-periodic response and provide a stability check for the harmonic balance technique, a transient transfer matrix has also been developed. The softwares for both of these newly developed transfer matrix techniques have been successfully verified for various non-linear rotor bearing systems using an established system matrix based transient rotordynamics software as the yardstick. These developments have been published in refereed journals. To investigate systems with rolling element bearings, appropriate bearing modelling which incorporates angular contact and rolling element inertia needed to be developed and incorporated into transient analysis softwares. Theoretical results from this were compared to data obtained from an experimental test rig which was designed to represent the salient features of an F/A-18 aircraft mounted accessory drive. The rig allowed for variation of bearing preload, unbalance loading and bearing support stiffness and could be run up to 17,000rpm. Full details of the design and commissioning are presented. Results showed better agreement than linear analyses but significant differences were encountered. Errors were largely due to estimated bearing parameters, in particular bearing damping, which was found to be a sensitive variable, so that agreement between theory and experiment was mainly qualitative. Other sources of error were those associated with experimental measurement and limitations of the bearing modelling. Further improvement of the bearing model is needed if better quantitative agreement is to be obtained between the predictions and experiment.

- Alicyclic diols can hydrogen bond in many different ways and yield most interesting structures. In this thesis, eight C2-symmetric diols 48-50, 78, 79 and 81-83 were synthesized and their crystal structures were determined. No less than seven of these show unusual solid state behaviour: 48 and 78 are inclusion hosts; 49, 50 and 78 form doubly-stranded hydrogen-bonded ladder structures, where there is a strong preference for each strand to be homochiral; 78, 81 and 82 undergo self-resolution during recrystallization; and 83 forms chirally pure crystals (but the material is still racemic). - One of the favourable supramolecular synthons for hydroxy compounds is the (O-H)6 cycle of hydrogen bonds. When this cycle is formed by a racemic compound, its enantiomers alternate down-up-down etc. around the cycle. No case of an (O-H)6 cycle involving chirally pure hydroxy compounds is known. These observations indicate a strong preference for the (O-H)6 cycle being constructed from achiral or racemic molecules rather than from chirally pure hydroxyl compounds. Racemic (??)-48 and (??)-92 which are already known to form (O-H)6 cycles in the solid state were prepared in chirally pure form and their X-ray crystal structures determined. No (O-H)6 cycles were observed for these homochiral diols. These findings confirm that the (O-H)6 motif occurs only for achiral or racemic compounds. - Similarly, the edge-to-edge eight-membered aryl C-H???N dimer involves either achiral molecules or those of opposite chirality. No chirally pure dimers of this type are reported. Racemic compounds 42-44 that are known to pack using the C-H???N dimer were synthesized in chirally pure form. No edge-to-edge eight-membered aryl C-H???N dimers were formed in the solid state. Hence this supramolecular synthon is only favoured for achiral or racemic compounds only. - Other major conclusions are that the cause of self-resolution is due to packing energy. In some cases it is likely that solvent choice, or solvent plus temperature selection, can be used to control self-resolution.

The purpose of this study was to ascertain the potential erosion impacts associated with ship movements in confined waters. The flow associated with a ship passage can be separated accordingly: (1) the propeller wake, (2) flow about the hull, and (3) associated waves. Each of these areas has been analyzed to determine their respective potential for causing channel erosion. Extensive field work was planned to determine the magnitude of the associated flows in a channel due to a shill) passage, but numerous problems developed that limited the amount of useful data obtained. As an alternative approach, use was made of data presented by other authors concerning channel flow effects caused by a ship passage. SOGREAH test results regarding Kiel Canal flows and ship related disturbances (Wasser-und Schiffahrtsdirektion Kiel, 1966) appear to be particularly applicable for the Coos Bay shipping channel because the channel dimensions and ship sizes in the two areas are approximately equal From the Coos Bay field work that was completed and from the extrapolations of the SOGREAH test results, the total erosion caused by ship traffic in Coos Bay was estimated to be insignificant compared to the natural erosion and deposition that takes place in the estuary. / Graduation date: 1977 / Best scan available.

In plume theory it is generally assumed that a plume issuing from a round source maintains a round cross section throughout. The consequences of this hypothesis are significant; this fact should motivate research into its validity. This paper investigates conditions and analyzes mechanisms that cause fluid plumes to undergo systematic deformation in their cross section. The process of deformation is referred to as differential growth. In search of support for these ideas some available plume experiments are investigated and some supporting evidence is found and presented. It is argued that ambient wind and variations in vertical buoyancy cause these effects. A rudimentary examination of plume physics tends to support these ideas. Approximations for these mechanisms are developed. For simplicity an important approximation is made in characterizing the plume cross section with an ellipse. By way of illustrating the effect of such cross sections on plume dynamics the computer plume model of Winiarski and Frick is adapted for differential growth. Based on the results of these modifications of the model compared with round plume results and compared with some plume data it is found that the modified model is able to predict behavior the conventional theory does not predict. / Graduation date: 1977
