Subsonic Wind Tunnel
Product Code : EL-FMLE-10681
QUICK ANSWER: The Subsonic Wind Tunnel is a small, computer-controlled wind tunnel designed for bench-top operation, in which air is drawn through a 150mm (6” nominal) square, 455mm-long working section by a variable-speed fan at the discharge end; a honeycomb flow straightener at the inlet and a 9.4:1 contraction ratio ensure well-developed airflow, giving an air velocity in the test section variable from 0 to 34m/s. The clear acrylic working section gives good visibility of the models under test and has model connection points in its sidewall and roof, and its entire base is removable to allow the insertion of large or complex models such as the Bernoulli Apparatus, Boundary Layer Plate or alternative models built by the user. A choice of water or electronic manometer banks, quick-release tube connectors and fastenings for easy model changing, and a simple flow visualization technique support a wide range of aerodynamics and airflow studies, on a 220-240V, single-phase, 50Hz, 10A supply.
The Subsonic Wind Tunnel module is a small wind tunnel designed for bench top operation; air is drawn through the working section by a variable speed fan at the discharge end of the tunnel. A honeycomb flow straightener is incorporated at the inlet, and a 9.4:1 contraction ratio ensures well-developed airflow through the working section, which is fabricated from clear acrylic to give good visibility of the models, with appropriate model connection points included in the sidewall and roof of the working section. A unique feature of the working section is that its entire base is removable to allow the insertion of large or complex models such as the Bernoulli Apparatus, Boundary Layer Plate or alternative models constructed by the user.
