wind tunnel design

A wind tunnel is a controlled testing environment used to study how objects, like aircraft or cars, interact with air. Its design includes a long, enclosed passage where fans generate steady airflow at specific speeds. Inside, models are placed to observe airflow patterns, pressure, and forces acting on them. To ensure accurate results, wind tunnels often have flow control features like screens and diffusers to stabilize the air, as well as instruments to measure forces and airflow characteristics. This setup helps engineers improve designs by predicting how objects perform in real-world conditions.
