Measuring Wind Tunnel Turbulence with a Sphere

Wind tunnel turbulence can be measured with a smooth sphere as a test model. Wind tunnel tests help engineers design vehicles and structures that will face airflow during use. The air flows are applied in a controlled way, and the model is usually a smaller version of the full-sized object.

In aerodynamics testing, wind tunnels are invaluable to determining the aerodynamic properties of various objects and scaled aircraft. Wind tunnel data is generated by applying a controlled flow of air to a testing model, which is mounted inside the test section. The testing model typically has similar geometry, but at a smaller scale, as compar...
