The Way Wind Tunnels Work and the Way They Are Used

We can feel the presence of the wind and airflow. Wind has to be measured to make sure there is proper ventilation in homes, offices and factories. Airflow should also be measured to see to it that buildings are safe (from harsh winds/hurricanes) and laboratories where people work with volatile chemicals are protected as well. Wind tunnels can be used to build and calibrate wind gauges that measure wind flow. These can also be used to know more about the aerodynamics of cars, trains and airplanes.

The Way They Work

Wind tunnels have a simple structure. They are long tubes placed within glass, metal, plastic or at times, an entire building. They consist of a high-powered fan on each end of the tube. One fan blows wind on the object while the other moves air out of the tunnel. In this way, there is no return flow to damage the data that is being collected. They can be small in size like a coffee table or large like a warehouse. Usually, they have many, different settings for testing objects or recalibrating wind gauges in various wind speeds. Therefore, the object/wind gauge will not get damaged as it works while the wind gauge will be capable of measuring the wind indoors or outdoors with precision and accuracy.

The Way Wind Tunnels Are Used

Wind tunnels are used in testing and recalibrating wind gauges that measure the force of wind outdoors, factories and ductwork of plants and offices. This helps prevent the ductwork from malfunctioning or being over pressurized from the air that moves through it. It also offers proper ventilation to offices and plants. Factories, plants and offices have to be properly ventilated to make sure of the employees’ respiratory health and in some cases, protect employees and products from harmful chemicals that penetrate the air. A lot of essential oil manufacturers come with elaborate ventilation systems that must do their best to prevent employees from becoming sick or injured.

Wind tunnels can also be used in measuring the aerodynamics of some objects and systems. Most cars and planes are put inside these structures before they are manufactured in volume. This is a way to test whether they are aerodynamic and will operate safely on the ground or air. The same is true for a lot of airplane engines. Most companies like Boeing and NASA make use of massive wind tunnels(as large as an entire building) in testing their airplanes as well as airplane engines. This is critical to guarantee the plane’s safety and efficiency.
