ATENG 11897 — Air Flow Studies Unit
Anodized aluminum frame and panels made of painted steel.
The unit includes wheels to facilitate its mobility.
Main metallic elements made of stainless steel.
Diagram in the front panel with distribution of the elements similar to the real one.
- Centrifugal fan, with speed control:
- Max. volumetric flow rate: 1800 m³/h.
- Max. motor power: 750 W.
It includes a plate with one orifice at the discharge side of the fan to carry out air jet dispersion practical
- exercises, orifice diameter: 30 mm.
- Long smooth test pipe, inner diameter 81.4 mm; length: 2500 mm approx. It includes:
Deflector in the inlet to prevent air-separation from the wall of the pipe and reduce the formation of
vortices.
Ten pressure tappings to measure the pressure gradient along the pipe.
Five stations to use the transverse Pitot tube and to determine the boundary layer growth and the
development of velocity profile.
ATENG 11897 detail
- Two Pitot tubes:
Pitot tube located at the discharge of the fan, attached and properly protected. It can be situated at different distances from the
- discharge orifice to study free jet velocity profiles:
- Horizontal: -150…150 mm.
- Vertical: -150…150 mm.
Pitot tube can be located in any of the different points of the test tube to perform an air flow analysis of the velocity profile inside the
- pipe section. This Pitot tube can also be located at different distances in the pipe to demonstrate the boundary layer growth:
- Vertical: -24…38 mm.
- Iris diaphragm, diameter: 40 – 97 mm. It includes two pressure tappings.
- Orifice plate, diameter: 50 mm.
- Two nozzles with different diameters, diameters: 50 and 70 mm.
Two bends and an angle may be fitted to the test pipe to compare pressure losses in fittings.
- Multi-tube inclinable manometer, which can be inclined to increase its resolution. It includes: 20 water tubes with a length of 500 mm and
- inner diameter of 6 mm, and a tank made of PMMA to fill it with water.
- Control panel:
Main switch.
ON/OFF Fan switch.
Fan speed controller.
Fan speed display.
Cables and accessories, for normal operation.
