Bernoulli visualization

This exhibit uses AR technology to visually display the airflow around the suspended ball to visitors, intuitively interpreting the Bernoulli principle. The exhibit mainly consists of a fan, LCD TV, camera, etc. After visitors press the button to start the fan, they place the ball at the air outlet to dynamically display the principle through the LCD TV. The media animation will simulate the distribution of surrounding wind force, helping visitors to clearly understand Bernoulli's principle. one Press the exhibit button to start the fan device 2 Place the ball close to the air outlet of the fan Observe the suspended motion state of the ball and watch the media animation demonstration on the LCD TV to understand the relationship between airflow and ball motion. Bernoulli's principle: after the fan is started, airflow is generated, and the airflow velocity at the outlet is faster and the static pressure is lower, while the airflow velocity around is slower and the static pressure is higher. This pressure difference forms upward lift, supporting the ball to suspend; This principle is also the core principle of aircraft takeoff • AR visualization: camera.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
