A small-scale axial fan demonstration unit, comprising of an inlet duct, the fan, an outlet duct and an adjustable aperture, all mounted on a stainless steel base.
Equipped with electronic measurement sensors for fan head pressure, flow-rate (via orifice plate), fan speed and air temperature.
Transparent ducts give visibility of the fan in operation.
Capable of being linked to a PC (not supplied) via a dedicated interface console (an essential accessory).
Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically.
Instructional capabilities
Measurement of inherent-speed machine performance in terms of static and total pressures, rotor speed and motor input power, as a function of inlet flow
Measurement of overall efficiency and estimation of impeller power efficiency
Measurement of performance at constant speeds
Introduction to similarity laws for scale-up
Comparison of student calculations with computer results
