Dr. Granlund is interested in unsteady experimental fluid mechanics, vortex dynamics and flow control.
The graduate students working under his direction are curious, motivated, and open to new ideas. A large part of research is to combine knowledge from several disciplines to solve difficult problems in easier ways. Dr. Granlund’s role as an advisor is to point students in the right direction and away from pitfalls while they train to become independent researchers.
Outside of work, Dr. Granlund enjoy hiking, bicycling and spending time with family outdoors.

Research Description
Dr. Granlund's long term goal is to gain a deeper understanding of separated unsteady, separated flows and develop physics-based low-order force models for maneuvering and control of air vehicles. Unsteady fluid mechanics exist in in several different areas such as helicopter rotor aerodynamics, wind turbines, Micro Air Vehicle flapping flight, high-rate maneuvering conventional aircraft, where the object is unsteady, as well as gusting air with unsteady inflow. In many of these research problems, the freestream has rarely been varied; it is usually assumed to be constant and uniform. Dr. Granlund's research expands the knowledge of how streamwise velocity fluctuations affect "standard" unsteady fluid dynamic problems.
