题 目(Title of Seminar): Strategies of flow control of turbulent separated and free shear flows
时 间：2016年 11 月4 日 10:00-11:00
We will present the two typical applications of flow control for turbulent flows. The first concerns the unsteady separation on a NACA 0015 airfoil by means of pneumatic VG.
The dynamics of the attachment/separation processes will be discussed. The second one will concern the control of a free shear layer with several frequencies of activation,
ranging from low frequencies to high frequencies. The problem of low/high frequency excitations will be discussed in the context of turbulent scales and energetic cascade.
Dr. JP Bonnet is emeritus researcher at CNRS, Laboratory PPRIME (physics of materials, energetic and engineering sciences) in Poitiers – France. He manages numerous studies on compressible flows with a Book (Gatski-Bonnet on turbulent high speed flows). He organizes several international meetings on turbulent flows control. He will be in 2017 Associate Editor of ‘International Journal
of Heat and Fluid Flows”. He is part of the new Europe-China H2020 programme ”DRAGY” for skin friction drag reduction.
