Modelling transient flow in hydropower stations

Modelling the movement of water through a hydropower station is an important tool for understanding this very complex behaviour, where water is pushed and pulled through long tunnels and spinning turbines, resulting in a vast range of pressures and speeds. There are generally two types of models: 1-dimensional (1D) models, which are simple and cost-effective, but do not provide adequate detail for the more complex features in the power station. The second type is 3-dimensional (3D) models, which are very detailed but cost both time and money.

Acute Impact of an Extremely Low Frequency Magnetic Stimulus on Human Neurophysiological Function

Power-lines and electric appliances are the main sources of daily human exposure to power-frequency magnetic fields (MF, 60 Hz in North America). In order to protect the public and workers from potential adverse effects, international agencies publish MF exposure guidelines based on the “best estimate” available regarding the levels producing an acute biological effects in humans, which is called magnetophosphenes (flickering lights perceived eyes closed in the dark while exposed to a strong MF).

Analyse comparative d’une formation en présentiel et d’une formation basée sur un jeu sérieux dans le cadre d’Hydro-Québec

Depuis quinze ans, Hydro-Québec organise des formations sur l’Initiation au code de sécurité des travaux Postes et centrales et Initiation aux risques d'induction, mise à la terre et foudre. Ces formations de trois jours s’adressent à toute personne appelée à intervenir chez Hydro-Québec. Visant un meilleur coût d’opportunité, Hydro-Québec a choisi d’intégrer une nouvelle modalité de formation constituée de deux jours de jeu sérieux suivis d’une journée en présentiel. Les jeux sérieux sont des jeux vidéo adaptés à l’enseignement.

Impacts of hydroelectricity production on aquatic ecosystems: Development of key environmental indicators for Life Cycle Assessment (LCA) approach

In boreal and temperate regions, dams are mainly constructed to provide ecosystem services such as hydroelectricity production. River impoundment and the alteration of natural hydrological regimes are suggested to be major disturbances to aquatic ecosystems. To meet long-term environmental objectives for sustainable development, Hydro-Quebec recently adopted the Life Cycle Assessment (LCA) approach. LCA is an ISO standardized approach assessing the potential environmental impacts of product, services and processes throughout its entire life cycle.

Development of an International consensual method for water use impact assessment in LCA

Cascades within the MITACS Elevation program are threefold: a. Ensure their industrial voice is represented on this international consensus building  process b. Being proactive, influence the process and anticipate the developments on the consensus around water footprinting methods c. Generate industry specific case studies to test  the method, ensure key problems are addressed and increase internal awareness Supporting the researcher that will lead the international process conducted under WULCA group is the mean of meeting the above mentioned objectives.

Feasibility of a pressure retarded osmosis process for Quebec electricity generation

Osmotic power or salinity gradient energy is one type of the renewable energies which is produced by mixing fresh water with salt water. This new environmental friendly energy based on the advantages such as carbon dioxide free and generating power continuously seems to be a good option in which to invest as it will be highly beneficial to Quebec. This project looks to develop expertise related to osmotic power. A pressure retarded osmosis (PRO) power test unit will be designed and installed in Quebec. This will be the first osmotic power system in North America.

Development of High Velocity Oxy-Fuel Iron Aluminide Coatings Reinforced With Hard Ceramic Particles for Wear Resistant Applications

This project aims at developing new coating materials exhibiting high oxidation, corrosion and wear resistance to addresses the specific needs of power generation equipment, which operate under severe erosion and abrasion conditions in corrosive environments.

Electrodialysis treatment of Kraft black liquo rusing Bipolar membrane

The production capacity of the Kraft process is one of the important measures in the pulp and paper industry. A promising method for increasing the production capacity of the Kraft process is to lower the load of the recovery boiler by means of extracting lignin from the black liquor (BL).

Effect of dam-rock interface irregularity of the seismic response of gravity dams

Dam failures may lead to catastrophic consequences, extending far beyond the immediate neighbourhood of the dam site due to sudden reservoir release or overtopping. The main objectives of this research project are: (i) to apply state-of-the-art simulation tools to investigate the seismic response of a real dam in Québec to formulate guidelines on the significance of including the effects of the irregularity of dam-rock interface and vertical component of earthquakes in the evaluation of the seismic response of dams.
