Low Speed Wind Tunnel L-2B
The L-2B facility is a low speed, open circuit wind tunnel of the suction type. It incorporates an air inlet, fitted with honeycomb and meshes, a two-dimensional contraction, and several interchangeable test sections of 0.35 m height, 0.35 m width and various lengths from 0.9 m to 2 m.
An Eiffel-type test section designed to reduce closed section wall interference is also available, as well as a moving ground belt for testing of road vehicle models in ground effect. The axial fan at the end of a circular diffuser is driven by a 4.4 kW variable-speed DC motor, providing a maximum velocity of 35 m/s. This facility is specially suited for Diploma Course projects and for preliminary investigations of tests to be carried out in larger facilities.
