Open Wind Tunnel

The Open Wind Tunnel is an educational and experimental aerodynamics system designed for studying airflow characteristics and aerodynamic behaviour around different test models under controlled conditions.

The wind tunnel generates a controlled stream of air through an experimental test section where different models and measuring accessories can be installed. This arrangement allows students to directly observe and measure important aerodynamic parameters while relating theoretical fluid mechanics principles to practical airflow behaviour.

One of the major experiments performed with the system is the determination of drag and lift coefficients for different models. Suitable measuring arrangements allow aerodynamic forces acting on a test body to be determined while airflow passes around it. Experimental data can then be used to calculate and compare lift and drag characteristics.

The apparatus also enables the investigation of pressure distribution on bodies immersed in airflow. Pressure measurements at different locations around a test model help students understand how body geometry and airflow influence local pressure conditions and aerodynamic loading.

Another important application is boundary layer analysis. Measurements can be taken close to a test surface to investigate velocity variation within the boundary layer and understand the influence of viscous effects on aerodynamic flow.

The Open Wind Tunnel can also be equipped for the investigation of flutter. This enables students to observe dynamic behaviour that can occur when aerodynamic forces interact with flexible or movable structures.

Wake measurement can be performed downstream of test models to investigate the disturbed flow region produced behind a body. Wake measurements provide useful information for understanding drag, velocity deficits, turbulence, and downstream flow behaviour.

For visual demonstrations, the system can be used with a fog generator for streamline visualization. Fog introduced into the airflow makes flow patterns more visible, helping students observe how air moves around different test bodies and how model geometry influences streamline behaviour.

With its ability to accommodate different accessories and test models, the Open Wind Tunnel provides a versatile platform for a wide range of aerodynamic experiments and demonstrations.

Micro Technologies supplies Open Wind Tunnels for engineering colleges, universities, polytechnic institutes, technical training centres, research facilities, and educational institutions requiring practical aerodynamics and fluid mechanics laboratory equipment.
