DESCRIPTION:Prof. Karen Mulleners\, Unsteady Flow Diagnostics Laboratory (
 UNFoLD)\, Institute of Mechanical Engineering (IGM)\, School of Engineerin
 g (STI)\, EPFL\nFace masks are recommended for in-person attendance in MED
  0 1418.\n\nAbstract: At UNFoLD\, we specialise in the experimental measur
 ements and data-driven analysis of unsteady vortex dominated flow interact
 ions with applications in bio-inspired propulsion\, wind turbine rotor bl
 ade aerodynamics\, and gust interactions. The unsteady flow conditions we 
 are interested in can be the result of temporal changes in the surrounding
  fluid flow velocity and direction\, e.g. due to gusts\, wakes\, or shear
  flows\; or it can be the result of the unsteady movement of the objects t
 hat interact with the flow\, e.g. pitching\, flapping\, or rotating wings
  and airfoils. The unsteadiness can be a blessing: it allows bumblebees 
 to fly despite having small wings\, and creates electrical power by rotati
 ng wind turbine rotors\; but it can also cause serious damage to the obje
 cts subjected to unsteady flow interactions: loss of lift and manoeuvrabil
 ity\, structural vibration and fatigue damage.\n\nIn this colloquium\, I 
 will present how we use experimental data to unfold the origin and develop
 ment of unsteady flow separation and vortex formation and how this aids to
  exploit the benefits and limit the harm caused by unsteady flows.\n\nBio
 : Karen Mulleners is an assistant professor in the institute of mechanical
  engineering in the school of engineering at EPFL since 2016. She is the h
 ead of the unsteady flow diagnostics laboratory (UNFoLD). She is an experi
 mental fluid dynamicist who focusses on unfolding the origin and developme
 nt of unsteady flow separation and vortex formation. Karen studied physics
  in Belgium (Hasselt University\, previously Limburgs Universitair Centrum
 ) and the Netherlands (TU Eindhoven). She received her PhD in mechanical e
 ngineering from the Leibniz Universität Hannover in Germany in 2010 for h
 er work on dynamic stall on pitching airfoils that she conducted as a memb
 er of the German aerospace centre (DLR) in Göttingen. Before joining EPFL
  in 2016\, Karen was a (non-tenure track) assistant professor at the Leibn
 iz Universität Hannover in Germany.
