Hand-Cranked Water Vortex (Vortex Decompressor)
★Exhibit Content: Vortex ★Interaction: Mechanical Interaction ★Operation: Turn the handwheel and gradually increase the cranking speed. When the impeller at the bottom of the cylinder reaches a certain rotational speed, a vortex forms in the liquid inside the cylinder. Please carefully observe the shape and characteristics of the vortex. ★Exhibit Description: The exhibit consists of a handwheel, a vortex generation device, a transparent container, etc. The vortex generation device is composed of water pipes tangent to the transparent container. The valve is installed at the bottom of the transparent acrylic cylinder. The top is not capped, the interior is hollow, and an impeller is installed at the bottom. When visitors participate in the interaction, they turn the handwheel, which drives the impeller to rotate, forming a vortex. ★Scientific Principle: A vortex has an important characteristic: at the same horizontal plane, the product of the flow velocity at a point and the radius at that point remains constant. That is, the closer to the center, the faster the flow velocity and the lower the pressure; the farther outward, the slower the flow velocity and the higher the pressure. Therefore, a vortex has a centripetal suction effect. Utilizing this characteristic of vortices, people have made centrifugal dust collectors, centrifugal fuel injectors, cyclone combustion chambers, etc.
