About This Product
A subsonic suction wind tunnel draws air through a contraction and a test section with a fan placed downstream, so the flow reaching the model is smooth and uniform. In aerodynamics and fluid mechanics laboratories it is used to measure flow velocity and its gradients in the test section, to read pressure differences around an aerofoil and to study the pressure gradient around a cylinder. Adding a lift and drag balance extends the work to force measurement on a model. School Lab Equipment India supplies the Subsonic Suction Wind Tunnel across India and can export it to Barbados, Côte d'Ivoire, North Macedonia, Argentina and Timor-Leste.
Frequently Asked Questions
Q1. What air speed does the Subsonic Suction Wind Tunnel reach?
The variable-speed fan gives air speeds from 1 to 45 m/s, with a maximum airflow of 45 m/s in the 230 × 230 × 500 mm test section.
Q2. What experiments can be done with it?
Measurement of flow velocity and gradients in the test section, pressure differences around an aerofoil and the pressure gradient around a cylinder. With a 2-component balance it measures lift and drag, and with a 3-component balance lift, drag and pitching moment.
Q3. What power supply does it need?
The tunnel is listed for 380/440 V, 3-phase, 50 Hz, with other voltages available on demand. The test equipment runs on 220 V single phase.
