University wind tunnel experimental teaching instruments and equipment, customizable.

The basic components of a wind tunnel include the tunnel body, the power section, and the measurement and control section.

2, Working principle: A power device is used to drive a controllable airflow through a specially designed duct, flowing over a stationary model placed in the test section to simulate the motion of an object in still air. The aerodynamic forces acting on the model are measured, and the flow phenomena on the model's surface and surrounding area are observed. Based on similarity theory, the experimental results are compiled into similarity parameters applicable to real objects. The test section is the central component of the wind tunnel, and its flow field should simulate the real flow field. The airflow quality, such as uniformity, stability (referring to the variation of parameters over time), and turbulence intensity, must meet certain standards. Wind tunnels are primarily classified according to the speed range of the test section. Different speed ranges result in variations in working principles, types, structures, and typical dimensions. This wind tunnel belongs to the Eiffel-type wind tunnel.
