John Lumley has most recently been involved in several projects with practical applications. He is developing low-dimensional models of the wall region of a turbulent boundary layer (using dynamical systems theory, among other tools) with an eye to controlling the boundary layer to reduce drag or increase mixing. The models will be used to predict stage losses and heat transfer in turbomachines. He is also exploring shape optimization in turbulent flows. These models and computational techniques can be used as tools in the design and evaluation of the next generation of commercial aircraft. |

| Biography |
|
Prior to coming to Cornell in 1977, Professor Lumley spent eighteen years at The Pennsylvania State University, where he became Evan Pugh Professor of Aerospace Engineering. In addition, he was in charge of research on turbulence and transition at the Applied Research Laboratory (which Pennsylvania State operates for the Naval Sea Systems Command). Lumley was a Fulbright senior lecturer at the University of Liege (Belgium) and a Guggenheim fellow at the University of Aix-Marseille and the Ecole Centrale de Lyon (France) in 1973. In 1982 he received the Fluid and Plasma Dynamics Award of the American Institute of Aeronautics and Astronautics. He was awarded the Fluid Dynamics Prize of the American Physical Society in 1990, and the Timoshenko Medal of the American Society of Mechanical Engineers in 1993. He is the recipient of two honorary doctorate degrees from the French University System, Paris. He is a fellow of the American Institute of Aeronautics and Astronautics and the American Academy of Arts and Sciences, and a member of the National Academy of Engineering. |
