报告内容简介：
Computational Aero-Acoustics (CAA) methods are designed to simulatenoise generation from complex flows. However, unsteady CAA computations arevery time demanding and most high order spatial discretization schemes arerather difficult to handle complex geometries. This lecture will firstintroduce two non-uniform time integration methods for efficient CAAcomputations. Then an optimized spectral difference scheme and a fluxreconstruction method will be described for the treatment of complex geometries.Finally, different aeroacoustic problems including jet, slat and acoustic linerwill be presented to demonstrate the capability of the developed high order CAAmethods.

Dr. Xiaodong Li is a professor in the School of Energy and Power Engineeringat the Beihang University (BUAA). He graduated from BUAA with Bachelor’s,Master’s and Ph.D.’s degrees in 1989, 1992 and 1995, respectively. He has beena guest scientist at German Aerospace Research Center (DLR) in 1997 andsubsequently at Technical University of Berlin. He established wideinternational collaboration network during the past 20 years. Dr. Li’s researchinterests are in the development of new theoretical and numerical methods foraeroacoustics, especially for jet noise, duct acoustics, turbomachinery noiseand airframe noise. Currently he is an Associate Fellow of AIAA and serves asan international member of the AIAA technical committee of aeroacoustics. Dr.Li also serves on the Editorial Board of the International Journal of Aeroacoustics.
