An Exergy-Based Framework for Advanced Energy Systems Development

“Exergy” is a Second Law principle that quantifies the work potential or quality of energy flows and storage. It allows for more nuanced energy systems analysis and development as a complement to traditional First Law (i.e., conservation of energy) analyses. The overarching basis for this assertion will be presented. Additionally, an example of the added insights afforded by exergy analysis will be given via a case study for an advanced compact energy system concept that entails solid oxide fuel cells. This investigation was performed during a faculty fellowship at the Air Force Research Laboratory and presented at the 2013 American Society of Mechanical Engineering fuel cells conference. Subsequently, relevance of the approach to other areas of interest (e.g., building thermal management, phase change materials) will be interactively discussed.

About the Speaker:

Dr. Comas Lamar Haynes is a faculty member of the Georgia Tech Research Institute and Joint Faculty Appointee at the Oak Ridge National Laboratory. His research includes modeling steady state and transient behavior of advanced energy systems, inclusive of their thermal management, and the characterization and optimization of novel cycles. He has advised graduate and undergraduate research assistants and has received multi-agency funding for energy systems analysis and development. Sponsor examples include the National Science Foundation, Department of Energy and NASA. Dr. Haynes also develops fuel cells and alternative energy systems curricula for public and college courses and experimental laboratories. Additionally, he is the co-developer of the outreach initiative, Educators Leading Energy Conservation and Training Researchers of Diverse Ethnicities (ELECTRoDE).He received his Bachelor of Science degree from Florida A&M University and his graduate degrees from Georgia Tech; and all of the degrees are in the discipline of Mechanical Engineering.
