Smoke wind tunnel experimental device
This is a specially designed small wind tunnel to visualize the airflow around a model. The compact device can be demonstrated in various locations, such as classrooms, regardless of the laboratory setting, and can be easily moved and stored when not in use. The airflow moves from the bottom to the top. Air entering from the bottom of the device passes through a contraction section and a comb-shaped nozzle, then enters observation ducts illuminated on both sides. The lighting clarifies the streamlines around the model. There is a variable-speed fan at the duct exit that adjusts the flow rate based on volume. A smoke generator is located beneath the device. Smoke (oil droplets) is produced by heated vegetable oil and carbon dioxide supplied from a tank, and is sent to the comb-shaped nozzle. From the comb-shaped nozzle, 23 streamlines are released to observe the airflow around the model.
