Wing-Surface Fluid Demonstrator
★Exhibit Content: Wind tunnel, wing shape and lift ★Interaction: Electromechanical interaction ★Operation: Press the "Power" button, rotate the handwheel, and observe the effects of the angle change of the wing model in the wind tunnel. ★Exhibit Description: The exhibit consists of a display stand, a prop board, and a wind device. Inside the glass cover of the display stand, a prop board imitating a wing shape is set up. Visitors press the button to start the wind device and can feel the wind generated inside the acrylic cover. The streamlines on the wing board will show different states according to changes in shape and angle. This helps understand the influence of gas flow on wing shape in wind tunnel experiments. ★Scientific Principle: What is the principle of wing lift? When air flows over the lower surface, it is "blocked" by the wing and forced to turn. Originally flowing backward, it now flows diagonally downward; when air flows over the upper surface, due to fluid viscosity, the air is still "guided" by the upper surface of the wing, so it naturally also moves diagonally downward.
