Rigorous Design of a Compact, Low-Speed, Open-Loop Wind Tunnel

Currently available literature regarding the design of fluid flow systems tend to focus on the specific system without providing a general guideline for how to address the design problem. This thesis focuses on developing such a general approach which is applied to the design of a wind tunnel meant for the University of Windsor. It is shown that, by applying the first principles of fluid mechanics to the problem, the components required, for operation of the wind tunnel within set constraints and requirements are identified. Numerical simulations are performed in two parts: 1) two-dimensional computational fluid dynamics simulations, which enable a parametric study of each component, and 2) three-dimensional computations, which provide a more accurate estimation of the performance of the wind tunnel. By following these steps, it is found that computational cost is greatly reduced by first sizing the components during the parametric study. The metrics used to assess the wind tunnel performance are the flow non-uniformity and the total pressure loss coefficient throughout the tunnel. The first principles based approach yields a set of components, respecting the constraints set while two-dimensional computations allows the determination of the wind tunnel dimensions and estimation of its performance, which is verified by a three-dimensional computation. Employing this approach, a successful wind tunnel design rated with a maximum volume flow rate of 12.9 m^{3}/s at a test section inlet velocity of 40 m/s with the ability to be attached to different test sections is achieved. This wind tunnel comprises a fan followed by a constant area duct leading to a diffuser, which is attached to a flow conditioner. The last component is a nozzle directing the flow into the test section. The wind tunnel operates with an estimated 8% flow non-uniformity at the nozzle exit together with a total pressure loss coefficient of 0.238 based on the test section inlet dynamic pressure

Policy responses to disaster management: a comparative case study of the BRICS countries to the COVID-19 pandemic.

Masters Degree. University of KwaZulu-Natal, Durban.Disaster management is a component that is responsible for ensuring the protection and safety of countries and their communities. The role of disaster management incudes, to organise the appropriate control mechanisms, allocate the necessary resources and follow the required practice policies. This is all done to prevent, prepare for, respond to as well as recover from a range of emergencies. Disaster management is utilised to respond to a range of disastrous events ranging from natural disasters, man-made disasters, biological disasters and technological disasters The COVID-19 pandemic presented a new set of challenges for countries to combat, which ultimately led to many revisiting their disaster management policy responses. Previous work has failed to address the disaster management policy responses that governments sought to implement particularly when dealing with pandemics. The main aim for governments was to implement effective disaster management policy responses which would result in reducing the spread and impact of the virus. For this, governments relied on restructuring existing disaster management policies to evoke greater powers to make decisions faster. This study sought to investigate the disaster management policy responses in BRICS countries through comparative case approach and SWOT analysis towards the COVID-19 pandemic. The study implemented a qualitative approach, secondary sources of information were used. Secondary sources of information such as articles, journals, books and government publications. These sources were fundamental towards this study because it provided the overall research that was examined in this study. Content thematic analysis was used to comprehend the information collected from texts to present arguments and grasp a coherent conclusion. Comparative case study approach was used for effective comparison among the chosen case studies. The formulation of themes was guided by the Disaster Management Model being mitigation, preparedness, prevention, recovery and response. The results of this study showed that the case studies possessed individual strengths and weaknesses. Due to the impact of the pandemic the policy responses varied based on population size, resources, leadership, accountability and preparedness. This concluded in varied disaster management policy responses that were effective during different stages of the pandemic

Phenomenon-based research in management and organisation science: When is it rigorous and does it matter?

Recently, the editors of Long Range Planning called for more phenomenon-based research. Such research focuses on identifying and reporting on new or recent phenomena of interest and relevance to management and organisation science. In this article, we explore the nature of phenomenon-based research and develop a research strategy that provides guidelines for researchers seeking to make this type of scientific inquiry rigorous and relevant. Phenomenon-based research establishes and describes the empirical facts and constructs that enable scientific inquiry to proceed. An account of the study of open source software development illustrates the research strategy. Rigorous phenomenon-based research tackles problems that are relevant to management practice and fall outside the scope of available theories. Phenomenon-based research also bridges epistemological and disciplinary divides because it unites diverse scholars around their shared interest in the phenomenon and their joint engagement in the research activities: identification, exploration, design, theorising and synthesis
