Wind tunnel is an appartus for producing a controlled stream of air for conducting aerodynamic experiments, The experiments is condudcted in the test section of the win tunnel and complete tunnel configrations includes setting chamber with screens, contraction cone, testing section diffuser and power section, aerodynamic experiments are conducted in the test section. Wind tunnel can be blow down or suction type or open circuit for low power consumptions, close circuit wind tunnel can be used.

A wind tunnel is an apparatus designed to produce a controlled stream of air for performing aerodynamic experiments under repeatable conditions. The experiment is conducted in the test section, where the airflow interacts with a model or component, allowing measurement of forces, pressure distribution and flow characteristics. A complete wind-tunnel configuration generally includes a settling chamber with screens, a contraction cone, a test section, a diffuser and a power section that drives the airflow. These components ensure uniform, stable and measurable flow for accurate aerodynamic analysis.

Wind tunnels can be designed as blow-down, suction-type or open-circuit systems depending on airflow requirements and available power. For applications requiring reduced energy consumption and improved flow quality, closed-circuit wind tunnels are preferred, as they recirculate the airflow and provide consistent test conditions. These tunnels are widely used in academic, industrial and research environments to evaluate aerodynamic behaviour, ventilation performance and flow-related engineering design parameters.
