Overview
A Wind tunnel is used to observe air flow around the sample or measure the forces exerted on the surface of the sample. It creates an artificial airflow with a constant velocity and direction. The sample is placed in the airflow to perform aerodynamic researches or experiments by measuring the interaction between the sample and the airflow.
Basic Knowledge about Wind Tunnels:
Each type of wind tunnel has the features mentioned below, and is selected according to the purposes of tests.
Return Flow Type (Gottingen Type)
- Airflow is stable because it is separated from atmospheric influence.
- It is energy efficient because no wind power goes outside of the tunnel.
- This type of wind tunnels is easy to be soundproofed.
Open Circuit Type (Eiffel Type)
Suction Type
- The effect of the fan is eliminated and ideal airflow is easily generated because the fan is located downstream.
Blow Type
- Samples and measuring equipment are easily prepared because the measuring section is open.
