ABSTRACT:
Methane gas is a marker for biologic activity, a greenhouse gas, and a fuel that is an important source of energy worldwide. The remote measurement of methane relies on the identifying the unique spectroscopic signature associated with mid-infrared emission and absorption due to vibrational-rotational energy transitions. In this talk, I will describe briefly the fundamentals of these transitions, two applications to planetary science, and laboratory experiments studying the distribution of fuel in high-speed combustion events.
Joe Shepherd is the C. L. “Kelly” Johnson Professor of Aeronautics and Professor of Mechanical Engineering, Emeritus at the California Institute of Technology in Pasadena, CA. He has been on the faculty at Caltech since 1993 and served on the faculty of Rensselaer Polytechnic Institute from 1986 to 1993. Prior to that, he was a staff member at Sandia National Laboratories from 1980 to 1986. He earned his PhD in Applied Physics from Caltech in 1981, and his BS in Physics from the University of South Florida in 1976.
Joe’s research interests have primarily been in the application of molecular and atomic physics, statistical thermodynamics, chemical kinetics, fluid dynamics and solid mechanics to various aspects of combustion, shock and detonation waves, and high-speed flows. His approach is to combine laboratory experimentation using imaging and other optical methods with analytical and numerical studies to obtain fundamental insights into nature and technology.
During his career, he has worked on a number of projects to investigate and improve the safety of nuclear power plants and waste storage or treatment facilities in the United States, Europe, and Asia, including the 1979 incident at Three Mile Island and the 2011 incidents at Fukushima Dai-ichii. His group carried out extensive research on aircraft fuel tank flammability, developing methods of characterizing ignition sources and characterizing explosive events. Researchers in the Explosion Dynamics Laboratory have made fundamental contributions to the study of detonation waves, hypersonic flow, thermal and other ignition processes, and response of piping systems and medical devices to detonations and shock waves.
