Richard C. Miake-Lye
Ph.D, Applied Physics, Stanford University

Dr. Miake-Lye's work is directed toward understanding the environmental impact of airplanes, focusing on the physical and chemical evolution of exhaust flowing from propulsion systems. Field studies, such as APEX1-3, AAFEX, and several military engine tests, as well as sub-scale physical models, and numerical models have been pursued to assess problems related to system performance, engine emissions characterization, and contrail formation. A tunable diode measurement technique for trace gas emissions has been developed and is being applied in support of the emissions characterization effort. In addition, a new Aerodyne measurement technology, the Aerosol Mass Spectrometer, is being applied to characterizing the particle emissions from aircraft engines. Additional advanced techniques are being developed for both particle and gaseous species measurements in parallel with on-going improvements in related microphysical modeling. One major thrust of these efforts is to understand the effects of emissions from gas-turbine engines powering the commercial aviation fleet, both existing and planned, on the global atmosphere and as a contributor to regional air quality. In addition to these research efforts, Dr. Miake-Lye serves on the SAE E-31 committee, Aircraft Engine Emissions Measurement, and was committee chair for five years. This committee writes Aerospace Information Reports and Aerospace Recommended Practices specifying measurement procedures for characterizing emissions from aircraft engines. He is currently Research Focal Point for Local Air Quality to the International Civil Aviation Organization's (ICAO's) Committee on Aviation Environmental Protection (CAEP), and supports its working groups on environmental issues.

Zhenhong Yu
Ph.D., Physical Chemistry, University of Missouri-Kansas City

Dr. Yu joined Aerodyne as a senior scientist in October 2007. His current research interests focus on the atmospheric measurements of the gas and particle-phase species involved in the formation and evolution of aerosols, which are generated in the exhaust streams of aircraft engines. Previously, he was a postdoctoral associate at Harvard University, where he worked on studying intermolecular interaction and molecular dynamics of molecular clusters by high-resolution molecular spectroscopy, as well as kinetic modeling of chemical evolution in interstellar medium.

J. Jay Peck
Ph.D., Aerospace Engineering, Massachusetts Institute of Technology

Dr. Peck is a Senior Engineer in CATD. With his Aerospace Engineering background, he is currently involved in several projects that require fluid dynamic design or thermal management. He is also participating in expanding the microphysicsal modeling capability to include volatile organic compounds in addition to sulfuric acid. Prior to joining Aerodyne, Dr. Peck developed a combustion system for micro-scale (“MEMS”) gas turbine engines for portable power generation as his doctoral thesis project at Massachusetts Institute of Technology (MIT). He demonstrated stable combustion of JP8 fuel within a volume of ~1cm3, proving that the micro-combustor can be used as a reliable heat source for micro-gas turbine engines as well as for solid-state heat-to-electricity conversion devices such as thermoelectrics and thermophotovoltaics. Dr. Peck’s research interest includes general heat and mass transfer phenomena, aircraft PM emissions, portable power generation, and Power-MEMS.

Greg Magoon
Ph.D., Chemical Engineering, Massachusetts Institute of Technology

The research interests of Senior Engineer Dr. Magoon include applied mathematics, cheminformatics, bioinformatics, "next-generation" sequencing, quantum chemistry, and modelling and simulation. For his doctoral thesis in the Department of Chemical Engineering at MIT, Dr. Magoon developed software tools for automated reaction mechanism generation, with a focus on improving parameter estimation during the mechanism generation process; these tools were applied to construct a detailed chemical kinetic model for JP-10 combustion. His recent work includes efforts to further refine understanding of JP-10 combustion through high-level ab initio quantum chemistry calculations. He also develops "next-generation" sequence data analysis tools and develops inverse modeling capabilities for atmospheric transport and dispersion.

The Center for Aero-Thermodynamics at ARI is active in a variety of research efforts in chemistry, combustion, and particle microphysics where coupled fluid flow and kinetics problems pose complex, interdisciplinary challenges in modeling and experimental measurement. State-of-the-art numerical tools are developed and applied to simulate and analyze phenomena ranging from combustion through aerosol formation and development. Advanced diagnostic measurement techniques are employed in sophisticated small-scale laboratory testing facilities at Aerodyne or taken to government or industry test facilities for problems ranging from engine emission characterization through exhaust system design. Our research efforts include the desulfurization of fossil fuels and the production of synthetic fuels from a variety of unconventional and renewable feedstocks, as well as inverse modeling to characterize emissions sources based on downwind measurements.

Government sponsors include: the National Aeronautics and Space Administration, the Federal Aviation Administration, the Strategic Environmental Research and Development Program, the Defense Advanced Research Projects Agency, Army, Navy and Air Force and by industry sponsors.
