William A. Sirignano serves as Professor of Mechanical and Aerospace Engineering and of Chemical Engineering and Materials Science and occupies the Henry Samueli Endowed Chair in Engineering at the University of California, Irvine. He received the B. Aero. Engineering degree from Rensselaer Polytechnic Institute and the M.A. and Ph. D. degrees from Princeton University. He has served as Dean, School of Engineering, University of California Irvine; George Tallman Ladd Professor and Department Head, Carnegie-Mellon University; and Professor, Princeton University. His major research and teaching interests include spray combustion, turbulent combustion and ignition, aerospace propulsion, fluid dynamics, and applied mathematics. SirignanoÂ's major forefront research accomplishments include analysis predicting periodic nonlinear oscillations with shockwaves in an unstable combustor; explanation of the nonlinear fluid dynamics associated with Helmholtz resonators; determination of admittance for oscillatory, three-dimensional nozzle flows; theory for condensed-phase behavior in flame spread above liquid and solid fuels; theory for ignition of combustible gas by a hot projectile; resolution of turbulent flame and propagation in reciprocating and rotary internal combustion engines; theory of droplet vaporization and convective heating with internal circulation; computational methods for spray flows; theory of droplet interactions in a dense spray; analysis of driving mechanisms for combustion instability in rockets and ramjets; conceptual advancements of turbine burners and miniature liquid-fuel-film combustors. He has over 400 research papers and about 250 research seminars and presentations. SirignanoÂ's awards and recognitions include National Academy of Engineering membership; Fellow status in AIAA, ASME, AAAS, and APS; AIAA Propellants and Combustion Award; ASME Freeman Scholar Fluids Engineering Award; AIAA Pendray Aerospace Literature Award; The Combustion Institute Alfred C. Egerton Gold Medal; Institute for the Dynamics of Explosions and Reactive Systems (IDERS) Oppenheim Award; AIAA Energy Systems Award; American Electronics Association, Orange County Council, Award; President's Award for Engineering Excellence in Service to Higher Education, Orange County Engineering Council; UC Irvine Alumni Distinguished Research Award; and United Aircraft Research Fellow. His professional service has included Chair, Microgravity Research Committee of NRC Space Studies Board; NASA Space Science and Applications Advisory Committee; AIAA Publications Committee; Chairman, AIAA Solid Rockets Technical Committee; Executive Committee, Treasurer, and Board of Directors, The Combustion Institute; President, IDERS; Series Editor, Combustion Science and Technology, Taylor and Francis; and Editorial Advisory Boards for Combustion Science and Technology, Combustion and Flame, Atomization and Sprays, Progress in Energy and Combustion Science, and Archivum Combustionis.
