  • Faculty Host: Dr. William Devenport
  • Abstract: Noise is a current major societal problem causing discomfort and stress-related health issues to the population. Aerodynamically produced noise hampers the societal acceptance, and consequently, the business development of renewable energy resources, e.g., wind turbines, and the environmental-economical balance of relevant airports, e.g., Schiphol in Amsterdam. In response to the increasing societal demand for increasingly silent engineering applications, the chair of the Engineering Fluid Dynamics Department of the University of Twente established a research line in Aeroacoustics.
  • This presentation gives an overview of current research and future targets in this research line. The presentation starts introducing the new UTwente aeroacoustic wind tunnel. Next, different techniques for construction of microphone arrays for noise source location are evaluated. Special attention is given to the possibilities, limitations of different constructions and its application in wind energy research. Lately, an overview of the ongoing research and a landscape of expected developments in the aeroacoustic field in Twente is discussed.
  • Bio: In 2007 Leandro de Santana graduated Aeronautic Engineer by the University of São Paulo, Brazil. In 2007 he started his career as a trainee at Embraer, working with aeroacoustics in the R&D department. Afterward, from 2008 till 2010 Leandro worked as Flight Test Engineer especially focused on Embraer military applications and products.
  • In 2011 Leandro moved to Belgium where in 2015 he obtained his Ph.D. degree from KULeuven working in a joint project with the von Karman Institute for Fluid Dynamics.
  • From 2015 to the present time, Leandro is an Assistant Professor in the University of Twente in the Netherlands. In his current position, he teaches disciplines such as Aeroacoustics, Introduction to Aircraft Technology, Aerodynamics and Flight Dynamics.
  • Leandro’s research is focused on three main lines: airframe noise, wind turbine noise, and UAV applications. Currently, Leandro is the principal investigator of the Silent Approach project, a joint effort involving Embraer, NLR, and DNW aiming at reducing the experimental uncertainty in industrial aeroacoustic wind tunnel tests. Furthermore, he cooperates with a range of wind energy companies performing aeroacoustic in field tests and investigations in the UTwnente Aeroacoustic Wind Tunnel. In the UAV sector, Leandro investigates the aerodynamics of the flight of a robotic bird in cooperation with the ClearFlight Solutions startup.
  • In his free time, Leandro enjoys to travel and know new cultures. He visited 50+ countries, he speaks 5 languages and currently is learning the 6th (Dutch).
