Model Reduction of Computational Aerothermodynamics for Multi-Discipline Analysis in High Speed Flows
… including: simple two-dimensional flow over flat surfaces up to three-dimensional flows over deformed surfaces with shock-shock interaction and shock-boundary layer interaction. An additional focus of this dissertation is on the implementation and computation of results using the developed …

On-line sensors for measuring the total ball and charge level in tumbling mills
… toe and shoulder angles were obtained from the surface vibration caused by the impact of the charge on the mill shell. The industrial scale experiments were performed at varied mill feed rate at constant ball load of 28%. In the pilot scale experiments, the Magotteaux ball mill at Frank …

Ground vibration from underground railways: how simplifying assumptions limit prediction accuracy
Noise and vibration from underground railways is a documented disturbance to individuals living or working near subways. Much work has been done to understand and simulate the dynamic interactions between the train, track, tunnel and soil resulting in numerical models which can predict ground-borne …

The study and development of distributed devices for concurrent vibration attenuation and energy harvesting
… on the broadband attenuation of structural vibration and, in the process, employs a new perspective of vibrational energy harvesting devices. The first part of the research studies and develops a continuously distributed vibration control device which combines the benefits of point …

Particle-Based Triboelectric Vibration Sensor for Speech Recognition and Remote Machine Condition Monitoring
Self-powered vibration sensors, particularly those utilising triboelectric nanogenerators, hold great promise for real-time monitoring of dynamic loads and structural health without external power sources. Based on the triboelectric effect and electrostatic induction, a triboelectric vibration …

Aircraft Anti-Icing Analysis: Water Droplet Dynamics Under High-Frequency Atomization and Superhydrophobic Effects
… levels. A novel approach uses the structure's vibration to induce atomization, a proposed active anti-icing method using high-frequency Piezoelectric Transducer (PZT) vibration and combines it with the passive method of surface roughness variation by fabricating superhydrophobic surfaces. The …

Deformation-assisted antifouling of surfaces
Fouling of surfaces occurs across many scales and applications, ranging from biomedical devices to ships, from membrane separation processes to ice formation on the wings of planes Chemical cleaning of the surfaces is often seen as the de facto treatment, but the drawbacks include the costs of …
