NHERI Wall of Wind Experimental Facility

The NHERI Wall of Wind (WOW) Experimental Facility (EF) at Florida International University (FIU) was funded by NSF to be a national facility that enables researchers to better understand wind effects on civil infrastructure systems and to prevent wind hazards from becoming community disasters.

About WOW

The NHERI WOW EF is powered by a combined 12-fan system capable of repeatable testing in up to 157 mph wind speeds through its flow management system. The unique advantage of the NHERI WOW EF is multi-scale (full-scale to 1:400) and high Reynolds number simulation of the effects of wind and wind-driven rain. This is accomplished using the twelve fans and a water spray system.


Wall of Wind Workshops

The Wall of Wind hosts biannual workshops. Learn more about upcoming opportunities, past events, and how to livestream facility experiments.
