Tabletop wind tunnel experimental device
This open-type suction wind tunnel allows for a wide range of experiments related to fluid dynamics, despite its compact design. It consists of a large bell mouth with a honeycomb, a two-dimensional converging nozzle, an experimental area (125x125mm), a diffusion section, a protective mesh, a variable-speed fan, and a silencer unit, achieving a flow with minimal turbulence. The included manometers (6 units) and two Pitot tubes positioned before and after the experimental area measure the wind speed and pressure distribution in the wake of the model. The experimental area has four sides made of transparent acrylic panels, with the front and back panels being removable. The device comes with a single force balance measurement system and three types of experimental models (a cylindrical model with pressure holes, a NACA0012 wing model, and a flat plate model), allowing for immediate experiments on drag or lift, as well as pressure distribution experiments around a cylinder. The drag or lift (N) is digitally displayed on the included display unit. Additionally, the single force balance measurement system can be mounted on the underside of the experimental area, enabling the measurement of drag (N) using original test specimens created with a 3D printer or similar methods.
