Cowen, Edwin (Todd)
Research Interests: Cowen has built an environmental fluid mechanics research program centered on four themes: environmental transport processes, water wave induced flows, lake hydrodynamics (physical limnology), and quantitative imaging techniques. He has developed experimental techniques, built new facilities, and undertaken basic research in: the dispersal of mass by jets and low-momentum point sources; scale-dependent dispersion, swash zone (the region of the beach face that is alternately dry and wet) turbulence; wave-structure interaction; exchange processes at embayment-lake connections; residence time in natural water bodies; internal waves in lakes and reservoirs, the effects of macrophytes on the mass and momentum transport processes, gas transfer by turbulence at an air-water interface, sediment suspension by turbulence at a sediment-water interface, and the remote sensing of discharge (flow rate) by optical means. Cowen's work on environmental turbulence, particularly the wake-wake interactions in macrophyte canopies, has lead to his recent push into the field of wind energy with research interests in wind turbine wakes and wind farm siting and optimization. Cowen is recognized as an authority in the areas of experimental measurements in fluid flows and environmental fluid mechanics and is a member of the editorial board of the journal Experiments in Fluids and an associate editor of the journal Environmental Fluid Mechanics.
