Speaker: Dr. Sanjiva K. Lele (Stanford University)
Title: "Large Eddy Simulations for Aeroacoustics"

Date: Friday, April 26, 2013
Time: 11:00 a.m.
Location: Gilman Hall 50 (Marjorie M. Fisher Hall)


Aeroacoustics concerns the generation and propagation of sound in fluid flows. Large eddy simulation provides an attractive approach to capture both the unsteady flow processes producing the sound and its propagation. We aim to highlight the technical challenges associated in doing so and the recent progress with examples from airfoil trailing-edge noise, wake-interaction noise and supersonic jet-noise. We stress that a suitable combination of accurate simulations of the non-linear unsteady flow and an acoustic propagation theory provide an effective tool not only for scientific investigations and share some highlights from this, but also for engineering design and analysis, in future.



Sanjiva Lele is a Professor in the Department of Mechanical Engineering and Department of Aeronautics and Astronautics at Stanford University. After his Batchelor’s degree from IIT Kanpur in India he received PhD from Cornell University. He was affliated with the NASA-Stanford Center for Turbulence Research from 1986-1989 and joined the faculty at Stanford in 1990. His research interests include diverse applications of fluid mechanics, turbulence, and aeroacoustics. He has received the F. N. Frenkeil award from APS-DFD, R.T Knapp award from ASME and the NSF-Presidential Young Investigator Award. He is a fellow of APS and served as an associate editor of the Journal of Fluid Mechanics from 1994-2004.
