MAE Department Seminar

B1220. Join the Mechanical and Aerospace Engineering Department for their upcoming seminar featuring Dr. Jason M. Anderson, a Distinguished Scientist in Hydroacoustics at the Naval Surface Warfare Center's Caderock Division! He will be presenting, "Characterizing Wall-Pressure Spectra beneath Turbulent Boundary Layer Flows overa. Wide Renoylds Number Range" Abstract: The fluctuating surface pressures due to the external turbulent boundary layer flows over large and/or high-speed vehicles, which are a source of undesired structural vibrations and acoustic sound radiation, are characterized over a relevantly wide range of Reynolds numbers, 3,000 10, by approximately 5 to 8 dB. This effort culminated in the development of an empirical model to predict the point-pressure and two-point pressure spatial coherence to enable computationally tractable predictions of structural vibration and acoustic response. Bio: Jason Anderson is the Distinguished Scientist in Hydroacoustics at the Naval Surface Warfare Center, Carderock Division. His research focuses on modeling and experimental measurements of low Mach number aeroacoustic mechanisms, such as propeller turbulence ingestion sound and turbulent boundary layer pressure scattering by surface discontinuities, as well as hydroacoustic mechanisms such as interactions between turbulent flows and flexible, fluid- loaded structures. Dr. Anderson has also led and supported efforts to design the COLUMBIA submarine class propulsor, update designs on VIRGINIA submarine class components for improved stealth, and inform the design of future attack submarines. Dr. Anderson has worked at Carderock since 2006, has been an active member of the AIAA Aeroacoustics Technical Committee since 2018, and he received his Ph.D. in mechanical engineering from Virginia Tech in 2003.
