Tornado

Tornado - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

Operating instructions: Press the "Start" button and observe the formation of a tornado. Function Overview: Exhibition items consist of smoke generating devices, exhaust fans, display racks, etc. The audience presses the start button to start the exhibition items demonstration. They can see that the water mist forms a funnel-shaped cloud column under the action of the exhaust fan, similar to the funnel-shaped cloud column generated by a tornado. Exhibition items reproduce the state of a tornado through physical simulation. The exhibition items simulate the motion of a tornado through interactive operations and the coordinated action of various devices in the exhibition booth. At the bottom platform of the exhibition items, there are devices such as water mist generators and water level monitors. The three columns of the exhibition items serve as both supports and side air vents. When participating, the audience presses the start button. When the exhibition items are activated, the water mist generator, tornado generator, etc. work simultaneously to create mist from the bottom of the device. Driven by the industrial fan and crosswind, the movement trajectory of the mist gradually forms a rotating upward trend and is finally sucked into the exhaust system. This process repeats to create a live simulation of the tornado shape seen by the audience.
