David Johnson
About
David Johnson is a Professor in the Department of Mechanical and Mechatronics Engineering at the University of Waterloo.
His research interests are in the development and application of Particle Image Velocimetry (PIV) to flows, the measurement techniques for internal flows, the turbulent recirculation flows, jet and nozzle flows, wind energy and wind turbines, large scale PIV and measurement techniques, as well as the incompressible flow turbomachinery.
Professor Johnson currently leads, and is also the founder of, the Wind Energy Research Group (WEG) at the university. The WEG works with wind turbine aerodynamics and aeroacoustics (noise). Professor Johnson and his team have several publications on incompressible flow turbomachinery, pump internal velocity measurements, fan design and performance measurement, and experimental and numerical studies of turbulent recirculating flows. Ever since working at the Ontario Hydro Research Division in the late 1980s, Professor Johnson has been involved in renewable energy research in Canada and Denmark.
In addition, he has lectured and published widely on measurement techniques for wind turbine aerodynamics, the performance of turbine airfoils, as well as developed innovative aeroacoustic measurement techniques for wind turbines.
