Faculty and students are invited to this free lecture. Dr. William (Mel) Roquemore, senior scientist for the Combustion for the Aerospace Systems Directorate of the Air Force Research Laboratory will discuss this exciting area of research. During his career Roquemore has pioneered the development and application of laser diagnostic techniques to study practical combusting flows. His team used advanced diagnostics techniques to establish a database for developing and evaluating models that that are still used to design combustors in today’s gas turbine engines. In the mid 1980s he invented the reactive Mie scattering visualization technique. The visualizations of combustion flows obtained by his team have received numerous scientific art awards, and appear in the book authorized by American Physical Society, “Physics in the 20th Century."
