The Fluid Mechanics Laboratory has 4 wind tunnels. Our largest wind tunnel has a 2 x 3 square meter test section with a 100 km/h max speed. Tunnels are equipped with 3D remote control mechanisms for traversing probes within the test section, and force plates and balances for measuring wind loads on structures. Pressure distribution on airfoils and from rakes of pressure probes are measured by rapid pressure scanners.
