Assessing The Economic Benefits Of Compressed Air Energy Storage For Mitigating Wind Curtailment, Brendan Cleary, Aidan Duffy, Alan O'Connor, Michael Conlon, Vasilis Fthenakis

Other resources

Renewable energy generation in the All-Island of Ireland (AII) is set to increase by 2020 due to binding renewable energy targets. To achieve these targets, there will be periods of time when 75% of electricity will be generated mainly from onshore wind. Currently, the AII system can accommodate a 50% maximum permissible instantaneous level of wind generation. The system operators must make system wide wind curtailment decisions to ensure this level is not breached. Subsequently, the ability to limit wind curtailment using large scale energy storage such as pumped hydroelectric energy storage and compressed air energy storage (CAES) is increasingly …

Comprehensive Understanding Of Nano-Sized Particle Separation Processes Using Nanoparticle Tracking Analysis, Desmond F. Lawler, Sungmin Youn, Tongren Zhu, Ijung Kim, Boris L.T. Lau

All Engineering Faculty Research

Understanding of nano-sized particle separation processes has been limited by difficulties of nanoparticle characterization. In this study, nanoparticle tracking analysis (NTA) was deployed to evaluate the absolute particle size distributions in laboratory scale flocculation and filtration experiments with silver nanoparticles. The results from NTA were consistent with standard theories of particle destabilization and transport. Direct observations of changes in absolute particle size distributions from NTA enhance both qualitative and quantitative understanding of particle separation processes of nano-sized particles.

The Epistemological Basis Of Engineering, And Its Reflection In The Modern Engineering Curriculum, Mike Murphy, William Grimson

Books/Book chapters

Perhaps unlike other professions, engineering is strangely difficult to define or describe. This is nowhere as evident as when an attempt is made to articulate its epis-temological basis. Engineering has a rich and complex ‘gene pool’ which goes back to when people first built shelters and shaped implements for agricultural purposes. Throughout the ages one constant characteristic of engineering has been its readiness to avail of whatever material is on hand together with whatever knowledge or skill is available to meet the challenge of enhancing an object or making something which nev-er previously existed. On occasion engineers have created new …

Air Change Rate Vs Airflow Pathway: Bioaerosol Containment And Removal In Patient Rooms, Kevin R. Grosskopf

Durham School of Architectural Engineering and Construction: Faculty Publications

Recent studies have shown that higher air change rates may have the unintended consequence of creating turbulent airflows that entrain high concentrations of infectious particles within the breathing zone, and possibly, breakdown pressure relationships necessary to contain the spread of infectious particles to other clinical spaces.

Use Of Fiber-Reinforced Cements In Masonry Construction And Structural Rehabilitation, Ece Erdogmus

Durham School of Architectural Engineering and Construction: Faculty Publications

The use of fiber reinforcement in traditional concrete mixes has been extensively studied and has been slowly finding its regular use in practice. In contrast, opportunities for the use of fibers in masonry applications and structural rehabilitation projects (masonry and concrete structures) have not been as deeply investigated, where the base matrix may be a weaker cementitious mixture. This paper will summarize the findings of the author’s research over the past 10 years in these particular applications of fiber reinforced cements (FRC). For masonry, considering both mortar and mortar-unit bond characteristics, a 0.5% volume fraction of micro fibers in type …

Ventilation Rates And Airflow Pathways In Patient Rooms: A Case Study Of Bioaerosol Containment And Removal, Ehsan S. Mousavi, Kevin R. Grosskopf

Durham School of Architectural Engineering and Construction: Faculty Publications

Most studies on the transmission of infectious airborne disease have focused on patient room air changes per hour (ACH) and how ACH provides pathogen dilution and removal. The logical but mostly unproven premise is that greater air change rates reduce the concentration of infectious particles and thus, the probability of airborne disease transmission. Recently, a growing body of research suggests pathways between pathogenic source (patient) and control (exhaust) may be the dominant environmental factor. While increases in airborne disease transmission have been associated with ventilation rates below 2 ACH, comparatively less data are available to quantify the benefits of higher …

A Review Of Approaches For Sensing, Understanding, And Improving Occupancy-Related Energy-Use Behaviors In Commercial Buildings, Hamed Nabizadeh Rafsanjani, Changbum R. Ahn, Mahmoud Alahmad

Durham School of Architectural Engineering and Construction: Faculty Publications

Buildings currently account for 30–40 percent of total global energy consumption. In particular, commercial buildings are responsible for about 12 percent of global energy use and 21 percent of the United States’ energy use, and the energy demand of this sector continues to grow faster than other sectors. This increasing rate therefore raises a critical concern about improving the energy performance of commercial buildings. Recently, researchers have investigated ways in which understanding and improving occupants’ energy-consuming behaviors could function as a cost-effective approach to decreasing commercial buildings’ energy demands. The objective of this paper is to present a detailed, up-to-date …

Engineering Ethics: Ontology And Politics, Eddie Conlon

Conference papers

“Ontology...acts as both gatekeeper and bouncer for methodology” (Archer 1995: 22). This exploratory paper, through a focus on the relationship between structure and agency, examines the underlying social ontologies informing the teaching, and researching of the teaching, of engineering ethics. It argues that current approaches are deficient and that Critical Realism can provide the basis for a more robust and inclusive research agenda for understanding engineering practice and the teaching of engineering ethics.
