Benjamin Lee Emerson II
Ben Emerson completed his Ph. D. in Aerospace Engineering from Georgia Tech in August, 2013. Since then, Ben has worked as a Research Engineer at the Ben T. Zinn Combustion Lab at Georgia Tech. Ben’s research portfolio includes projects on combustion instabilities, alternative fuels, and combustion system R&D with a core focus and motivation of cleaner combustion. Ben’s research primarily consists of three core competencies, which are experimental combustion system development, combustor diagnostics, and combustion theory and modeling. Ben’s combustion system development work spans a wide variety of applications, from small lab-scale burners to combustor rigs that test full-scale gas turbine combustor hardware. His combustor diagnostics work encompasses the state of the art optical diagnostic techniques for reacting flow field measurements and imaging, and aims to implement those techniques in both laboratory-scale and large-scale rig tests. Finally, Ben’s combustion theory and modeling work is geared towards analysis of experimental datasets, development of reduced-order engineering tools, and the development of a suite of hydrodynamic stability analysis tools. Together, these core competencies form the pillars of Ben’s research, which facilitates the design of cleaner-burning combustion systems.
Professor Emerson's teaching focuses on core aerospace engineering subjects at both undergraduate and graduate levels, emphasizing combustion, propulsion, and fluid mechanics. His instruction integrates theoretical foundations with practical applications to prepare students for research and professional practice.
Professor Emerson's research focuses on combustion systems for propulsion and energy. His background is fluid dynamics of combustion systems. Today, Professor Emerson has extended his research to R&D of future propulsion systems, management of pollutant emissions, and thermal management. This includes experimental testing and development of novel combustion diagnostic methods. It also includes thermoacoustic modeling and hydrodynamic stability modeling.
