Air Flow Studies

Air Flow Studies

• The unit is self-contained and only requires connection to a single-phase electrical supply.
• Turbulence in the 80mm diameter test pipe is minimised by locating the pipe at the inlet of the centrifugal fan.
• A profiled bellmouth inlet prevents air-separation from the wall of the pipe at the entrance and straightening vanes suppress the formation of vortices.
• Tappings along the test pipe allow the pressure gradient to be measured with air velocity variable up to a maximum of 35m/s.
• A Pitot tube can be traversed across the pipe at five locations to allow boundary layer growth/development of velocity profile to be examined.
• Air flowrate is determined from differential pressure measurements across an orifice plate or two different inlet nozzles.
• Different bends and elboes can be fitted to allow frictional losses in fittings to be compared.
• Air jet dispersion experiments are carried out on the discharge side of the fan.
• A Pitot tube can be traversed laterally (across) and longitudinally (along) the jet to measure the changes in velocity as the jet disperses.
• All pressure measurements are performed using a bank of fourteen manometer tubes that can be inclined to increase sensitivity.
• An instruction manual is supplied that describes how to perform the air flow experiments and interpret the results, as well as how to install, commission and maintain the equipment.
