Model Test Basins

IIHR has three large model test basins: one 30 meters by 27.5 meters, one 27.5 meters by 20 meters, and a third, which has been designed with special flow and metering capabilities, 39.5 meters by 15 meters.

Ice-Engineering Laboratories

The Ice-Engineering Laboratories of IIHR comprise five cold rooms capable of operating at temperatures as low as -45 degrees Centigrade in which are located the ice towing tank/model basin and icing wind tunnel (described separately, below), as well as a 12.2-meter-long, 0.6-meter-wide tilting flume; a custom-built ice-scraping machine; a 1-meter-wide, 0.75-meter-deep, 6-meter-long specimen tank; and a 50kN servo-hydraulic mechanical testing machine, with electronic feedback control and full-load, stroke, and strain control.

Icing Wind Tunnel

The portable wind tunnel is 11 meters long, with a 0.6-meter-square working section, and is equipped with a vaneaxial fan driven by 20-HP motor which produces wind speeds of up to 23 meters/sec.
