The wind tunnel saves time and money compared with full-scale wind tunnels or airborne laboratories, and it offers a wide variety of experiments. The wind tunnel gives accurate results and is suitable for undergraduate study and research projects. TecQuipment offers a comprehensive range of optional models and instrumentation, including a computer-based data acquisition system. Air enters the tunnel through an aerodynamically designed effuser (cone) that accelerates the air linearly. It then enters the working section and passes through a grill before moving through a diffuser and then to a variable-speed axial fan. The grill protects the fan from damage by loose objects. The air leaves the fan, passes through a silencer unit and then back out to atmosphere. A separate control and instrumentation unit controls the speed of the axial fan (and the air velocity in the working section). The control and instrumentation unit also includes manometers and electrical outlets to supply electrical power to other optional instruments. The working section of the tunnel is a square section with a clear roof, sides and floor. The sides are removable. The floor and each side panel has a special position to support the optional wind tunnel models. Supplied with the wind tunnel are a protractor and a model holder to support and accurately adjust the angle of any models fitted. A Pitot-static tube and a traversing Pitot tube fit on the working section, upstream and downstream of any models. They connect to the manometers of the instrumentation unit (or other optional instruments) to show pressure. A metal frame supports the wind tunnel. The frame includes lockable castors for convenient mobility. Electronic sensors on the optional wind tunnel instrumentation can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®, not included). VDAS® allows accurate real-time data capture, monitoring, display, calculation and charting of all relevant parameters on a suitable computer (computer not included). Standard Features • Supplied with a comprehensive user guide • Two-year warranty • Manufactured in accordance with the latest European Union directives Experiments A wide variety of subsonic aerodynamics experiments (some need ancillaries), including: • Flow past bluff and streamlined bodies with pressure and velocity observations in the wake • Investigations into boundary layer development • Influence of aspect ratio on aerofoil performance • Performance of an aerofoil with flap, influence of flap angle on lift, drag and stall • Pressure distribution around a cylinder under sub and super-critical flow conditions • Study of characteristics of models involving basic measurement of lift and drag forces • Study of the characteristics of three-dimensional aerofoils involving measurement of lift, drag and pitching moment • Study of the pressure distribution around an aerofoil model to derive the lift and comparison with direct measurements of lift • Drag force on a bluff body normal to an air flow • Flow visualisation Essential Services Electrical supply (three phase): 200 VAC to 240 VAC 50 Hz/60 Hz (26 A) or 380 VAC to 440 VAC 50 Hz/60 Hz (21 A) Space needed: Solid, level floor – allow at least 2 m of free space around the inlet and 4 m at the outlet Operating Conditions Laboratory environment Storage temperature range: –25°C to +55°C (when packed for transport) Operating temperature range: +5°C to +40°C Operating relative humidity range: 80% at temperatures < 31°C decreasing linearly to 50% at 40°C Specification Nett dimensions and weight (assembled): 3700 mm x 1065 mm x height 1900 mm and 293 kg Approximate packed volume and weight: 4.9 m3 and 450 kg Working section: 305 mm x 305 mm, and 600 mm long.
