Optimisation de conception multi-fidélité des pales des turbines hydroélectriques

Du point de vue de la production d’énergie, la composante mobile de l’éolienne, le conduit, joue un rôle clé dans le fonctionnement d’une turbine à eau. Dans la situation concurrentielle actuelle des marchés énergétiques déréglementés, il existe une forte demande pour des coureurs plus efficaces capables de résister à des conditions d’exploitation sévères. Les méthodes traditionnelles de conception par essais et erreurs dépendent en grande partie de l’expérience des concepteurs et nécessitent toujours de longs cycles de conception. Dans ce projet, une nouvelle méthodologie d’optimisation de conception a été développée, utilisant une combinaison d’évaluations très précises et d’évaluations modérément précises peu coûteuses dans un cycle de conception approprié, afin d’intégrer leurs avantages et d’atténuer leurs faiblesses, en ce qui concerne des limites importantes en conception industrielle telles que le temps et le coût. Cette méthodologie robuste permet de prendre en compte plusieurs objectifs et contraintes de conception différents afin d’obtenir des runners haute performance. Puisque la majorité des centrales électriques canadiennes fonctionnent avec des turbines hydrauliques, même d’une amélioration de quelques points de pourcentage de l’efficacité et de la durabilité des conduits, des millions de dollars supplémentaires peuvent être gagnés chaque année.

Embedded security markers in metal additive manufacturing parts and detection via high-frequency ultrasound systems

Metal additive manufacturing (AM) technologies are now frequently used in the aerospace, automotive, medical, and energy sectors for fabricating end-use components. The digital nature of the supply chain involved for metal AM production becomes increasingly susceptible to numerous types of cyber- and cyber-physical threats. There is a need for developing security and traceability markers embedded in products, as well as low-cost non-destructive testing (NDT) methods such as ultrasonic testing (UT) for detection of such security markers benchmarked against computed tomography (CT) characterization data. The collaborative project between FUJIFILM VisualSonics and the Multi-Scale Additive Manufacturing Laboratory will investigate the design tradeoffs for embedding such security features to ensure manufacturability via metal AM, material performance, as well as meet UT detection limits based on the newest generation of phased array ultrasonic probes. The outcomes of this program have the potential of multidisciplinary academic discovery and opening a new market sector for VisualSoni

Polymer electrolyte membrane fuel cell catalyst layer degradation

Clean electrochemical energy conversion is critically needed to build energy security that reduces Canada’s reliance on fossil fuels. The polymer electrolyte membrane (PEM) fuel cell is a particularly important part of a clean energy future as an attractive alternative to the internal combustion engine for transportation applications. PEM fuel cells offer zero local emissions, fast-start ups, and use of clean hydrogen that can be produced from renewable energy sources, such as wind and solar. However, the widespread adoption of PEM fuel cells in Canada is currently hindered by high costs and limited lifetimes, largely stemming from the membrane electrode assembly (MEA), which includes expensive platinum. For this project, the University of Toronto (Prof. Bazylak) and Ballard Power Systems Inc. developed a new partnership to elucidate the sulphonic degradation of the ionomer and coverage of platinum catalyst sites through ex situ and operando imaging, electrochemical performance characterization, and transport property analysis.

Multilingual Voice Recognition

Have you ever imagined a world where you can control everything at home and at work with your voice, even without having to read an instruction manual? Speech technologies based on artificial intelligence models promise to make that happen by teaching machines to recognize voice. However, these systems currently support only a few languages, and it remains a particular challenge to support languages for which large datasets do not exist. The proposed research will explore various state-of-the-art deep learning techniques to improve the performance of voice recognition for low-resource languages. This will help Picovoice to provide the same quality of service for diverse users and help language communities, where language is the only means of expression, to access important information they could not otherwise obtain.

Monitoring Stress Changes and Microseismic Events in Pillars During Potash Mining

Mining-induced stress in the area around tunnel openings represents a major design consideration in potash mines. In the past, induced stress has been monitored using an array of techniques derived from the hard rock mining industry, one of the key assumptions being linear-elastic deformation behaviour of the rock. When using these methods in a soft rock like potash, issues can arise with the accuracy of these assumptions. The proposed research will build on a recent project that developed improved methods for stress measurements in potash, and will supplement stress change measurements with microseismic monitoring technologies that can track yielding and creep in pillars by detecting the acoustic energy released when cracks develop. The results will lead to better methods for measuring the response of pillars to mining operations, which in turn will enable refinement of the models used to predict pillar response. Improved monitoring and modeling methods will allow more proactive engineering controls to be implemented at lower cost than reactive methods.

Stationary methanol steam reforming to hydrogen fuel for fuel-cell filling stations

Renewable hydrogen (H2) carriers such as methanol (MeOH) can be reformed back into H2 and is a fundamental chemical conversion for the long-term viability of the H2 economy due to its high density and ease of transportability compared to H2. MeOH is an especially important carrier as it is a simple C1 chemical that can be produced from solar-PV-generated H2 and direct-air-captured CO2 with a current commercially practical solar-to-fuel efficiency of 10% from renewable solar energy. MeOH steam reforming (MSR) in stationary systems next to H2 fuel-cell filling stations can eliminate the need for on-board mobile reformers and the former systems can be more robust in terms of attaining strict H2 product specifications. MeOH, with properly handling, is also a safe, lossless and a compact medium for long-term H2 storage. Both thermal- and photo-catalysts are viable options for achieving stable, long-term performance of stationary MSR systems.

Wild blueberry geospatial image analysis

We will develop complex image analysis processes to advance and tighten our current processes and more accurately and speedily identify bare spots and in addition develop new processes to identify specific weeds that cause problems in wild blueberry fields. Using spatially accurate drone photography of wild blueberry fields the intern would use custom programming logic to develop image analysis software code to identify entities within those fields. Foreign entities include bare ground, weed species and grasses. Once identified these entity areas would be converted into polygons and stored in a geospatial database for use in developing prescription maps.
