Samueli School Names Interim Dean
Dimitri Papamoschou, Ph.D., professor of mechanical and aerospace engineering, was recently named interim dean of The Henry Samueli School of Engineering at UC Irvine. Papamoschou joined UC Irvine in 1988 as an assistant professor, served as chair of the Department of Mechanical and Aerospace Engineering from 2002 to 2005, and as the Samueli School’s associate dean for academic affairs since 2007. He also served briefly as the school's acting dean in 2008.
Papamoschou has established himself as one of the leading experts in high speed flows and aeroacoustics. Most of his research is experimental in nature, with strong theoretical and computational foundations. His research contributions began during his Ph.D. studies at the California Institute of Technology in the late 1980s with thesis work on supersonic mixing layers, a flow of relevance to the propulsion of hypersonic vehicles. Following his Ph.D. studies, Papamoschou continued to investigate mixing layers with the discovery of fast and slow propagation modes that have a direct impact on mixing and noise generation. In the mid-1990s he began his involvement in the field of jet aeroacoustics, investigating the fundamental processes of sound emission from turbulent jets and developing new concepts for noise suppression for aircraft engines. He also invented new methods for mixing enhancement for high-speed flows, with applications including the suppression of infrared signatures from jet engines. More recently, he has developed special implementations of microphone phased arrays for identifying and localizing the noise sources in turbulent high-speed jets. From such measurements, he has constructed models for the noise source that are being used in conjunction with the boundary element method for the prediction of jet noise shielding for the Blended Wing Body airplane.
Papamoschou is a Fellow of the American Institute of Aeronautics and Astronautics (AIAA), serves as an associate editor for the AIAA Journal, and is actively involved in several additional organizations and scientific journals. He is the inventor of five U.S. patents in the areas of jet noise suppression and mixing enhancement.
