In this study, experimental tests and Computational Fluid Dynamics are used to investigate the aerodynamic performance of two types of track-based racing cars. After the literature study, where automotive aerodynamics is discussed in very general terms, the air flow beneath a Formula One Grand Prix Racing Car is investigated. This is achieved by fitting the under-tray of a 30% scale model of the Parmalat Forti Ford FGO 1-95 with surface-static pressure ports and testing the model in a rolling-road wind tunnel. By varying a number of model parameters, it is found that the wheels significantly alter the pressure distribution under the floor of the racing car at positions away from the centre-line. It is shown that the front or rear wheel sets are independently sufficient to induce the flow changes. The addition of the other set then only produces milder and more local changes. The numerical part of the floor investigation is aimed at reproducing the centre-line flow pattern by solving the full Reynolds-Average Navier-Stokes equations over a two-dimensional curvilinear grid of the isolated floor. Two algorithms, Roe's flux-difference splitting method and the commercial package, STAR-CD which employs the SIMPLE algorithm and a two-equation turbulence model, are used to solve the governing equations. It is found that although the correct trends are observed when two different ride heights are simulated, absolute correlation is inadequate despite the use of experimentally-controlled boundary conditions. The simulations are however used to demonstrate the saturation in downforce with increasing vehicle speed. In order to improve numerical accuracy, a second study was launched where the effect of including the centre-line profile of the complete vehicle is investigated. To reduce the amount of detail a 1/12th scale model of a generic BMW Touring Car is used. Experimental data in the form of centre-line surface-static pressure coefficients are used for numerical correlation. The data is obtained by testing the three-dimensional model in a wind tunnel fitted with a stationary-road raised-platform floor. To establish continuity, the experimental data is used to show the similarities between the pressure distribution on the centre line of the open-wheel and the closed-wheel racing car. The effect of a rear-mounted aerodynamic device on the downforce is also discussed. The numerical investigation using the SIMPLE algorithm of STAR-CD and three high Reynolds-Number turbulence models, is based on the centre-line profile of the experimental model. It is seen that although qualitative correlation exists in areas around the car, quantitative agreement is less positive. Discrepancies are found to be most significant under the floor. It is shown that the influence of the three dimensional flow field on the experimental results are unlikely to cause satisfactory correlation. It is suggested that, in order to improve correlation, a new investigation is launched aimed at refining the numerical model. An outline for the new study is presented and includes simulations indicating the dependence of the computational solution on the density of the grid and on the user-definable turbulence parameters. / Dissertation (M Eng (Mechanical Engineering))--University of Pretoria, 1999. / Mechanical and Aeronautical Engineering / unrestricted

There were two primary goals in this investigation. The first goal was to determine if results from field tests (time-trials and a Conconi incremental test) are related to performance in mass-start long-distance bicycle races. The second goal was to investigate inter-relationships among field test variables. The testing variables measured were critical velocity (CV), Conconi anaerobic threshold (AT) velocity, 4mM AT velocity, fatigue index, peak blood lactate, and anaerobic work capacity. Participants were USCF 30 category 1 through 5 cyclists. Participants performed one 20.75 km and two 10.37 km all-out tests in the field. They also performed an incremental test. The tests were performed at one-week intervals. Results from the field tests were compared to recent mass-start racing performance. Results indicated that Conconi AT velocity was related to performance in a 161-km race. There was also a relationship between 4mM AT velocity and CV and between Conconi AT velocity and 4mM AT velocity. It was concluded that field tests might provide information about performance ability in mass-start long-distance bicycle races.

'Betting by the Book' details the steps taken in, and results obtained from, an examination of the processes followed, especially in Australia, of those persons who bet on thoroughbred horseracing. The work briefly describes the evolution of the practice of this form of gambling and details the extent of the activity in the Australian nation. Note is made of the obvious limited amount of attention previously given to the topic by academia. Using illustrations of the extent of the complexity and resulting uncertainty of outcome in selecting winning horses the study finds that the consequential behaviour of almost all those who bet is the adoption of a co-ordinated process of selection commonly referred to as a system. As hypothesised the study found three major categories,viz., logical, naive and superstitious. Sub-types of the three categories, devised as a part of the study, are listed and defined. Unexpectedly the work brought to attention the finding that most bettors, even those following logical systems, will, at times, adopt superstitious practices. Examples are provided of logical, yet simple, selection systems that could be beneficially adopted by those persons who would otherwise follow naive and superstitious systems of selection. Finally the study notes the considerable opportunities that exist for the education of bettors. / Master of Arts (Hons) (Gambling Studies)

Inflammatory Airway Disease has been reported in young racehorses worldwide. The aim of this study was to determine the prevalence of airway inflammation in an actively racing population of horses and to describe and quantify the degree of lung lesions in this population of horses. The Ontario Death Registry program provided a unique opportunity to evaluate the lungs of actively racing horses that died or were euthanized due to catastrophic injuries while racing or training. Lung sections of 95 horses were included in the study and evaluated using a previously validated histological airway scoring system. Additionally, staining with Toluidine blue and immunohistochemical labeling was performed on a subset of horses to further characterize the inflammation. Inflammatory cell infiltration, smooth muscle hyperplasia and hemosiderin were commonly found. The airway lesion scores were significantly higher in the caudal and dorsal sections of the lungs than in other areas. There was no correlation between the individual scores and either breed, sex, age, cause of death or performance index. The inflammatory and smooth muscle scores were normally distributed and the hemosiderin score was not. The inflammatory cell infiltration was composed of mononuclear cells, with increased number of mast cells and eosinophils in 3/20 and 12/95 horses respectively. Immunohistochemical labeling showed the inflammation around the airway to be composed of 41.0% CD3-positive T cells and 5.8% CD79a-positive B cells. In addition to the airway findings, inflammatory cell aggregates were observed around the pulmonary blood vessels and in the alveolar septa in 67/95 and 71/95 horses respectively. In conclusion, this study provides a histologic evaluation of a population of actively racing horses in which airway inflammation is a common finding.
