NHERI’s University of Florida wind hazards facility is one of the world’s largest and most diverse suites of experimental infrastructure. Funded by the National Science Foundation, the UF’s boundary layer wind tunnel is located within the Powell Family Structures and Materials Laboratory. In June and July 2021, the DesignSafe Radio podcast features interviews with NHERI at UF facility director and principal investigator Jennifer Bridge, who details the capabilities UF wind tunnel and the research it makes possible. Professor Jennifer Bridge describes the flow field modulator, a new piece of equipment at the facility that greatly enhances the capabilities of the BLWT. The FFM is a bank of 319 very fast, individually controlled fans that can simulate transient events like wind gusts, downbursts, and thunderstorm winds. It can also replay wind events (called time histories) with data collected in the field, for example by the UF’s “storm chaser” team and its mobile weather towers. The facility is unique in its scale. Bridge explains how the FFM opens up wind engineering research to many new questions, with many new possibilities for discovering how different wind profiles affect structures.

There are just endless possibilities with what we can do, because of the number of fans, because of their flexibility and responsiveness. There’s just alot that we can do in this facility now that we weren’t able to do before.”-Jennifer BridgeRelated links:NHERI’s University of Florida experimental facilityVideo overview of the wind tunnel facility located within the University of Florida’s Powell Family Structures and Materials Laboratory.Work at UF helps engineers design structures that enable Floridians to survive extreme wind events.
