Small wind tunnel experimental device 305
This open-type suction wind tunnel can conduct a wide range of experiments related to fluid dynamics while maintaining a compact design. It consists of a large bell mouth, a two-dimensional converging nozzle, an experimental area (305x305x600mm), a diffusion section, a protective mesh, an axial fan, and a silencer unit, achieving a flow with minimal turbulence. The control unit (desktop type) regulates the rotational speed of the axial fan and controls the flow velocity in the experimental area. The wind tunnel and control unit, mounted on a caster-equipped frame, are designed to be very compact, making it easy to change their arrangement. Various options can be added according to the experimental objectives. The optional data automatic collection system VDAS (sold separately) can display measurement data in real-time on a computer (sold separately) and can calculate and graph the collected data, facilitating smooth progress in experiments.
