Computational Fluid Dynamics Study of High Energy Incidents Inside and Above Buried Underground Vaults

When a transmission cable joint in an underground vault undergoes an electrical failure this event can result in a high energy event and trigger a shock wave. Rapid and extreme pressure build up inside a manhole can cause a 200kg vault cover launching out as a dangerous projectile, which is referred as manhole incidents. The safety and reliability evaluation of the power cable joint in an underground vault has always been challenging with quite complex electromagnetic-thermal-mechanical coupling field.

Diagenetic history porosity evolution of the sandstones and carbonates around the Labrador?Port au Port Group boundary, Belle Isle, Western Newfoundland

The proposed project investigates the diagenesis of the lowermost Port au Port carbonates in Western Newfoundland. Few earlier studies suggested that the carbonates vary from lime mudstones of low energy to grainstones and rudstones of high energy shallow-shelf settings. The study will allow the reconstruction of full diagenetic history of the basin and factors that controlled the precipitation of cements and dolomitization that influenced the net rock porosity as well as the timing of precipitation of those cements during basin history.

Exergoeconomic Optimization of Advanced Compressed Air Energy Storage Technology (A-CAES)

Development of energy storage has been identified as one of the most important features of our rapidly evolving energy grids. While the significance of flexibility it provides is well understood, commercialization remains non-trivial. Advanced Compressed Air Energy Storage (A-CAES) is founded on well-known scientific principles that have been combined and applied in a novel way. These innovative systems are complex, each component with its own opportunity for optimization.

Optimization of Wastewater Treatment anaerobic digestion processes.

This project will test a variety of operating conditions used in anaerobic digestion (AD) in wastewater treatment (WWT) plants. The purpose is to identify optimal conditions for AD treatment process. Optimization of AD process would increase production of biogas for production of renewable energy, increase yield of bio-products for agriculture use, reduce WWT plant operating costs, and would decrease carbon footprint of municipal WWT plants. This study will use SENTRY-AD™ technology to monitor microbial activity under various treatment conditions.

Perovskite Solar Cell Development

The concern regarding the environmental impacts of climate change due to the consumption of fossil-fuels for our daily energy needs has notably increased over the past decade, resulting in a rapid increase of renewable energy implementation. The solar energy industry in particular has seen exponential increases in production worldwide.

ATCO Home of the Future and DSO Orchestration

The intern will be part of the ATCO Electricity Innovation Team and will support in delivering novel next generation prototypes that will define the future of the electricity grid in Alberta, broader Canada and globally. Some of the current projects in the portfolio includes smart EV charging, artificial intelligence based microgrids, home of the future and power systems technologies for making the electricity grid autonomous and smart. The student will be part of a horizontal team structure and will report directly to the Innovation Director.

Quality and degradation assessments of polymer-lined thrust bearings by indentation and tribological testing

Current needs for renewable and emission-free technologies imposes hydroelectric power plants to generate power in a predictable and reliable fashion. Replacing metallic to polymeric coatings in thrust bearings allows hydroelectric turbines to operate at a wider range of operation parameters. However, the sensibility of polymeric materials to the manufacturing method imposes important uncertainties on the performance and longevity these materials can have in service conditions.

MEPOWSS Wastestream Analysis

This project involves the characterization and assessment of a settling and evaporative pond system used to treat wastewater generated by the Melville Potable Water Supply System (MEPOWSS). The plant is currently being upgraded with a change in treatment processes and increased capacity that will impact the ability of the pond system to treat the new wastewater stream. The pond system consists of five pond cells in series, and current influent includes backwash from a greensand-filter and electrodialysis reversal (EDR) waste streams.

Techno-Economic Feasibility of Wastewater Heat Recovery for Cold Climates like Canada

Wastewater is an abundant and severely underutilized energy source in North America. Sewers experience predictable flow profiles and nearly constant temperatures between 18 ?C and 20 ?C year-round. When wastewater is used in conjunction with heat pumps, it can serve as an energy source and sink to provide both heating and cooling to buildings. Therefore, there exists the potential to extract significant amounts of thermal energy from the wastewater using heat exchangers, resulting in substantial economic and environmental benefits.

Measurement-based Distribution System Models for Distributed Energy Resources Control

The integration of significant capacities of distributed energy resources (DERs) such as renewable wind and solar generation for a more sustainable energy future creates several challenges to the reliable and efficient operation of power distribution systems. These include: (i) Uncertain and intermittent nature of renewable generation compromises power quality for end-customers.  (ii) Up-to-date distribution system network topologies are not well known and their real-time monitoring is limited. As a result, effective management of DERs is challenging.
