  Computer Controlled Aerodynamic Tunnel

  * Adequate size for demostration tests and teaching. * Suitable for three-dimensional models.* Test Chamber builts with transparent materials. * Low operation and maintenance cost. * Suitable for smokes visualization test. * AC motor-ventilator gropu, monophasic, with frequency variator. *The Aerodynbamic Tunnel of 1200*1200 mm section for testing, witha longitude of 2000 mm is of the Eiffeltype, aspirate and of open circuit, and allows us to carry out tests of measuring formces and aerodynamic field on models of structures, construcitons, land vehicles and small planes. * Its power plant, formed by 4 standard type ventilators, of 10 CV of power each one and 900 mm in diameter, has kept the final cost of the product low, while at the same time that assuring a simple and economicmaitenance. Nevertheless, this aspect does not prejudice the quality of the vein, of great uniformity and low turbulence level, thanks also to the adequate design of the contraction, neither does it affect the speed that is reached, this being about 36m/s in a vacuum.

  Pipe Friction Apparatus

  The experimental set-up can be used on its own or with the Basic Hydraulics Bench. A supply of water is all that is required for operation. The unit is suitable for measuring pipe friction losses for laminar and turbulent flows. The experimental set-up is clearly laid out on a training panel. For investigations on laminar flow, a head tank is used for the water supply, whilst for turbulent flow, the supply is provided via the Basic Hydraulics Bench directly (or the water mains). The water flows through a pipe section, the flow is adjusted using reducing valves. The connection to the required measuring device is made via pressure tappings.

  Computer Controlled Water Tunnel

  Water tunnel of 500*500mm, principal characteristics: * Adequate Size for flow visualizations on standard models of planes. * Useful for teaching and development projects. * Top quality vein, uniformity and low turbulence level. * Low operation and maintenance cost. *The water tunnel of 500*500 mm, of low turbulence level, is specifically designed for carrying out visualization tests on threedimensional models, though, of course, they can also be used on two-dimensional models. *As it is a closed circuit, it operates continuously and uses the same water, although it may be necessary to renew it once it has lost its transparency due to the use of colorings. However, if the technique of the hydrogen bubble is used as tracer this problem can also be avoided. *Its dimensions and low operating costs make it suitable for teaching as well as for research or industrial use. Assorted systems for registering images and taking measurements can be incorporated when necessary.

  Pitot-Static Tube Apparatus

  It is possible to move the Pitot-static tube across the entire cross-section of the pipe and thus measure the pressure profile. The position of the measuring tip relative to the bottom of the pipe can be read on a scale. The Pitot-static tube can be connected to any differential pressure manometer using hose connections. Differential pressures up to approx. 50mbar are possible when using the pump .The water supply is provided either from the laboratory mains or using the (closed water circuit).
