At ten o’clock in the morning on the November 4, 2016, Prof. Ulf Michel in DLR deliver a report in School of Power and Energy Room 225 in ChangAn Campus, the theme are “Introduction to Jet Noise” and “Why Large Scales Are the Dominating Source of Jet Noise”.
In the report for “Introduction to Jet Noise”, Prof. Ulf Michel showed the two different experiment results in single jet for static and flying. He analysis the reasoning of shock wave noise and its regular. Prof. Ulf Michel said the noise come from the shear layer.
In the report themed “Why Large Scales Are the Dominating Source of Jet Noise”, Prof. Ulf Michel mainly talked about the turbulence physical mechanism which will cause noise, especially for the large-scale turbulence structure of physical mechanism. Finally, Prof. Ulf Michel summarized the low noise aircraft design work in the future. After the meeting, students actively asked questions and they got satisfied answer from Prof. Ulf Miche.
Prof. Ulf Michel is a famous scientist in the field of aeroacoustics, He has worked for DLR, TU-Berlin, NASA's Langley research center, George Washington university in USA, University of Pennsylvania, Prof. Ulf Michel won the 2012 CEAS award because of his outstanding work in the field of aeroacoustics.
