Assistant Professor
Ph.D. (2003), Virginia Tech

Research Interests: Experimental fluid mechanics and vortex dynamics of unsteady motions leading to reduced-order models

Granlund received his M.S. in vehicle engineering from the Royal Institute of Technology in Sweden and a Ph.D. in aerospace engineering from Virginia Tech. Prior to joining the NC State faculty, he was a research engineer at the Air Force Research Laboratory at Wright-Patterson AFB in Ohio.

Presently, he studies the influence of streamwise velocity fluctuations on airfoils undergoing unsteady pitching and plunging. This is a natural extension of the “dynamic stall” problem and it applies mainly to helicopters and wind energy. Another topic is the theoretical concept of apparent mass and under what conditions it can be treated as a separate entity from circulatory force and off-body vortices.
