Multiphase Interactions
Multiphase flows are made up of a combination of the different states of matter, e.g. solids in liquids, liquids & gases, solids in gases, plasmas & gases, and so forth. These flows are all around us - wind driving the formation of ocean waves, debris flows and landslides occurring after a saturating rain, the bubbly flows associated with boat propellors,, sediment transport in streams and rivers - and the inherent complexity of these natural and engineered examples mean these flows are still very active topics of study. SAFL researchers use experimental facilities like CloudIA, the wind tunnel, and our assorted flumes and channels to help quantify the nature and behavior of different multiphase flows, while also using numerical techniques and simulations to better visualize these interactions and predict their behavior.

Wind Turbine Generated Sound
Posted
As the wind energy sector grows, environmental impacts and public perception become increasingly important. One common public concern about wind energy farms is wind turbine-generated noise.A major component of this project project was to provide technically defensible data characterizing wind turbine-generated noise and the human response to wind turbine-generated noise.
Development of tower and foundation assessment tools for utility-scale wind turbines
Posted
Wind turbine operators must asses turbine foundation structural health after extreme weather events, or before repower projects. SAFL engineers worked with Barr Engineering to design an inexpensive, noninvasive, and portable system for assessing wind turbine foundation health.
Detection and Perception of Sound by Eagles and Surrogate Raptors
Posted
Could acoustic deterrents be used to prevent eagle and raptor collisions with wind turbines? Researchers from a wide range of backgrounds and institutions worked together on this project to begin acoustic deterrent research for the Department of Energy. This project mapped the hearing range of raptors, collected and categorized eagle calls and vocalizations, and evaluated bald eagle response to various synthetic and natural sounds.
