About Open Circuit Wind Tunnels

Designed for precision aerodynamic testing, our high-speed open circuit wind tunnels deliver exceptionally smooth, low-turbulence airflow for research, development, and educational applications. The open-loop design draws air directly from the laboratory environment, ensuring flexible installation and cost-effective operation without recirculation complexity.

Engineered for adaptability, these systems can be configured to suit constrained spaces such as low ceilings, narrow access points, or facilities with structural obstructions. From compact laboratory units to large-scale research tunnels, we offer both standard models and fully customized solutions.

FAQ's of Open Circuit Wind Tunnels:

Q: How is flow uniformity maintained across the test section?

A: Flow uniformity is achieved using a precision-engineered nozzle and contracting cone in combination with flow straighteners. This design ensures that air velocity variation remains within 1% across the entire test section, providing highly consistent testing conditions.

Q: What types of educational or laboratory applications are suitable for this wind tunnel?

A: These wind tunnels are ideal for studies in aerodynamics, fluid dynamics, drag and lift measurement, and flow visualization. Common users include research laboratories, engineering institutes, and universities looking for reliable, repeatable airflow for experimental or teaching purposes.

Q: When is digital data acquisition available, and what sensors are supported?

A: Digital data acquisition is available as an optional upgrade. The system supports integration with various digital sensors for velocity, pressure, and temperature measurements, enhancing experiment documentation and real-time analysis.

Q: Where can this wind tunnel be installed, and what power requirements are needed?

A: The wind tunnel is suitable for installation in research labs, teaching facilities, and engineering workshops. Standard models require power supplies of either 220-240 V or 380-415 V, and consume between 3 kW and 12 kW, depending on the chosen configuration.

Q: What is the process for customizing the test section dimensions?

A: Customization begins with a consultation to identify your specific testing needs. Test section sizes can be tailored-from 300 mm x 300 mm up to 600 mm x 600 mm-during manufacturing, ensuring a bespoke solution for your projects.

Q: How does the digital speed controller enhance usage and safety?

A: The digital speed controller allows precise fan speed adjustments and displays real-time performance data. This helps maintain desired test conditions and includes additional safety features like an emergency stop, enhancing both operational safety and measurement accuracy.

Q: What are the key benefits of the modular steel frame and powder-coated finish?

A: The heavy-duty modular steel frame provides high structural integrity and adaptability for various accessories or modifications. The powder-coated finish offers excellent resistance to corrosion and physical wear, ensuring long service life and minimal maintenance.
