Junction flows occur when a boundary layer encounters a wall-mounted obstacle and are a source of unwanted noise for a wide range of engineering applications that include air, water, and land vehicles, wind turbines and turbomachinery.  To investigate this flow-induced noise source, the sound produced by two types of junction flows will be examined in this seminar: a wall-mounted finite length cylinder and a wall-mounted finite length airfoil.  Noise and flow measurements have been taken in an anechoic wind tunnel at the University of Adelaide at a range of flow speeds and for a variety of aspect ratios (length to cylinder diameter or airfoil thickness ratio) to determine the influence of these parameters on flow topology and noise generation.  The experimental data give improved insight into the underlying sound generation physics and can be used to validate numerical predictions of junction flow noise.

Biography:

Dr. Danielle Moreau is a postdoctoral research associate with the Flow and Noise Group at the School of Mechanical Engineering at the University of Adelaide.  She obtained her Ph.D. from the University of Adelaide in 2010 and was awarded a University Postdoctoral Research Medal for her Ph.D. research on virtual sensing in active noise control.  Danielle's current field of research is experimental aeroacoustics and focuses on the understanding and control of flow-induced noise.  She has more than 50 research publications and is currently a visiting Fulbright Scholar at Virginia Tech.
