  1. Wear of fine pearlite, nanostructured bainite and martensite

    Abrasion is a form of wear prominent particularly in the agricultural, mining, mineral and transportation industries. The cost of abrasive wear to the national economy is estimated to be about 1% of the gross national product, and it can compromise the safety and reliability of engineering …

  2. Aluminium foam production using calcium carbonate as a foaming agent

    The current state of the art with regards to the production of metallic foams is reviewed, with melt-based processes identified as the most promising for cost-effective large-scale production. The potential for metal carbonates as an alternative to currently-used titanium hydride foaming agents is …

  3. Fast upper body pose estimation for human-robot interaction

    This work describes an upper body pose tracker that finds a 3D pose estimate using video sequences obtained from a monocular camera, with applications in human-robot interaction in mind. A novel mixture of Ornstein-Uhlenbeck processes model, trained in a reduced dimensional subspace and designed …

  4. Secondary flows in centrifugal compresser impellers

    Detailed flow measurements made in a 1 metre diameter, shrouded, centrifugal (Ghost) impeller running at 500 rpm are presented. Relative velocities and rotary stagnation pressures $(p*=p-\frac{1}{2}\ρω^{2}r^{2}+\frac{1}{2}\ρW^{2})$ were measured on five cross-sectional planes between the impeller …

  5. Erosion-oxidation of mild steel in a fluidized bed environment

    This thesis is a contribution to research into erosion-corrosion investigating the rapid wastage of in-bed heat exchanger tubing in fluidized bed combustors. Two main new areas of research were investigated; erosion-corrosion of mild steel in a temperature gradient and erosion-corrosion modelling. …

  6. Towards a silent fan: an investigation of low-speed fan aeroacoustics

    The noise (unwanted sound) from fans of all sizes, operating in close proximity to people, can be a design constraint due to annoyance or, in the worse cases, health damage. Of the total noise, aeroacoustic noise – produced by unsteadiness in the air – often represents a significant source and is …

  7. The effects of natural convection on low temperature combustion

    When a gas undergoes an exothermic reaction in a closed vessel, spatial temperature gradients can develop. If these gradients become sufficiently large, the resulting buoyancy forces will move the gas, i.e. there is natural convection. The nature of the resulting flow is determined by the Rayleigh …

  8. Frequency-domain modelling of floating wind turbines

    The development of new types of offshore wind turbine on floating platforms requires the development of new approaches to modelling the combined platform-turbine system. In this thesis a linearised frequency-domain approach is developed which gives fast but approximate results: linearised models of …

  9. Pulsed field magnetization of composite superconducting bulks for magnetic bearing applications

    Permanent magnets are essential components for many devices such as motors, which currently account for 45 % of global electricity consumption, generators and also superconducting magnetic bearings used for applications such as flywheel energy storage. But even the most powerful rare-earth magnets …

  10. Development and characterisation of a copper-based oxygen carrier for chemical-looping with oxygen uncoupling (CLOU)

    … rate constant was also determined in the present research, and the kinetic parameters were used in a numerical model to predict the behaviour of the oxygen carriers in a fluidised bed reactor. Excellent agreement between theory and experiment was found, confirming that the kinetic parameters …

  13. Some aspects of magnetohydrodynamics

    This thesis is an account of various phenomena caused by the interaction of the motion of electrically conducting fluids with magnetic fields. Such phenomena, the study of which is usually known as Magnetohydrodynamics (MHD), occur on a galactic, planetary or laboratory length scale; however in …
