Biography

Brian Polagye is an associate professor in the Department of Mechanical Engineering and the Director of the Pacific Marine Energy Center, a collaboration between the University of Washington, Oregon State University, and the University of Alaska Fairbanks. His research focuses on marine renewable energy conversion and its environmental effects, with the ultimate goal of developing cost-effective, sustainable approaches.

Education

  • Ph.D. in Mechanical Engineering, University of Washington, 2009
  • M.S. in Mechanical Engineering, University of Washington, 2005
  • B.S. in Mechanical Engineering, Princeton University, 2000

Research Statement

Brian Polagye's research group focuses on the conversion of marine renewable energy resources (river, tidal, and ocean currents, as well as waves) to mechanical power. One thrust area is optimizing the hydrodynamics and control of conversion systems, primarily through laboratory experiments and field demonstrations. A second thrust area is developing and applying instrumentation necessary to characterize marine energy sites, with emphasis on underwater sound and integrated instrumentation systems.

Current research topics include:

  • Studying the hydrodynamics of cross-flow current turbines to increase individual turbine and array power yields
  • Studying the hydrodynamics and control of multi-body wave energy converters
  • Developing low-cost drifting instrumentation packages for volumetric swarm sensing
  • Developing integrated instrumentation systems for marine energy projects
  • Measuring the acoustic characteristics of marine energy converters
