Ces dernières années, le biobutanol a attiré l’attention dans le domaine de la recherche car ses propriétés sont supérieures à celles l’éthanol telles que sa valeur énergétique et son indice d’octane, il peut donc être un substitut de l’éthanol dans l’essence sans toutefois impliquer les problématiques généralement associées à l’éthanol (tel que l’hygroscopicité). De plus, […]

With recent high energy consumption rates, the awareness has been increased for thermal energy storage systems to reducing cooling loads. Referring to literature potentials and limitations, the research hypothesis can be formulated as ‘Developing a free cooling system of phase change material (PCM)-to-air heat exchanger, utilizing both convection and radiation heat transfer modes, can maintain […]

Extensive urbanized land surfaces, anthropogenic heat emissions, and lack of vegetation and tree cover contribute to the formation of distinct urban climates where warmer air and surface temperatures intensify outdoor heat exposure and thermal discomfort for pedestrians. To assess outdoor thermal comfort in urban environments, mean radiant temperature (Tmrt) is a commonly used indicator. The […]

Thermoelectric materials can be used to convert heat into electricity. The conventional method of fabrication for this type of application is to first compress the powder form of the material with heat followed by machining into rectangular prisms. Using two different compositions in the method described, one of negative-type and one of positive-type is to […]

Rivers provide important services to people in the form of agricultural irrigation, hydroelectric power generation, and recreation. However, many of these benefits require dams and river control at the expense of natural systems. Rivers in Spain are of particular interest because globally Spain has the most dams per person. This project will look at the […]

The Arctic Sustainable Energy Futures Toolkit will be a print and web-based guide for communities to follow when developing their comprehensive community energy plans. This step-by-step toolkit will transfer knowledge using best practices, resource guides, case studies, videos, worksheets, and templated pathways to help communities create and implement their energy visions. In addition, the Toolkit […]

Le groupe turbine-alternateur est l’une des parties les plus importantes d’un réseau électrique. Afin de faire fonctionner un réseau électrique en toute sécurité, il est essentiel de modéliser les groupes turbine-alternateur avec précision. Parce que les données dynamiques des groupes turbine-alternateur sont souvent inexactes, incomplètes ou même indisponibles. Il est avantageux que le processus d’identification […]

La simulation en temps réel de système d’électronique de puissance et de réseau électrique exige de faibles pas de calcul afin d’obtenir une précision sur les phénomènes transitoires. Pour répondre au besoin de sa clientèle, OPAL-RT technologies offre des produits de pointe qui sont contraints par un problème non trivial, les délais de communication. La […]

The safe operation of a dam, such as Mactaquac, necessitates regular integrity monitoring over the structure lifespan. Optical fiber temperature sensing can provide seepage monitoring throughout a dam structure providing the operator with location specific seepage rates. Since the monitoring will be continuous over time and potentially operate over the lifespan of the dam operators […]
