AFM 10 MODULAR AIR FLOW BENCH AND ACCESSORIES

 

A mobile bench providing the base unit for a wide range of air flow experiment modules

  • Air flow bench with variable air flow control and wide range of optional experiment modules available for a complete course in air flow.
  • Small Scale wind tunnel, ideal for student experiments, lecture theatre demonstrations and project work. Versatile, easy- to fit and change experiment modules.
  • Includes a textbook – First course in Airflow –by Professor E.Markland
  • Compact and mobile, with a worktop and shelves
  • No installation only single-phase electrical supply needed (and simple exhaust for waste smoke for the AF 17)

 

AFM 10

 

The main part of the equipment is the Air flow Bench AFM-10. This is a small-scale wind tunnel with an electric fan and adjustable air flow control. You need this first, you then choose and buy the additional experiment modules (AFM11 to AFM 18) that you need, fitting them to the Air flow Bench to do the experiments.

 

 

DESCRIPTION – AIRFLOW BENCH

 

A fan delivers atmospheric air through a flow-control valve to a plenum chamber. Some of the optional experiment modules fit to the opening in the plenum chamber.

Alternatively, Supplied as standard (and fitted), there is an aerodynamically shaped contraction that provides a smaller opening for other experiments. Strong but easy-to-use toggle fasteners hold the experiment modules to the plenum or the contraction, So that users need no extra tools to fit most experiments.

Discharge from the experiments is normally downwards. The air passes down through an outlet in the bench top and exhausts at the back of the bench. For experiments with smoke, users can fit flexible ducting to the exhaust to direct waste smoke safely away.

 

RECOMMENDED ANCILLARIES

 

Multitube Manometer (AFM 10a) – A multitube manometer to measure several pressures at the same time. It is useful for most of the experiments modules.

 

SPECIFICATIONS

 

Air flow: 30 m/s in 100x50mm working section (9m3/min)

 

EXPERIMENTS

 

  • When used with the optional experiment modules :
  • Demonstration of Bernoulli’s equation (AFM11)
  • Demonstration of a turbulent jet (of air) (AFM12)
  • Demonstration of boundary layer (AFM13)
  • Flow around a bend (AFM14)
  • Jet attachment (AFM15)
  • Flow visualization (smoke) (AFM16)
  • Pressure distribution around a symmetrical aerofoil (AFM17)

 

ESSENTIAL SERVICES

 

Floor space needed:

1.5 m x 1.5 m

 

ELECTRICAL SUPPLY

 

Single phase 230 VAC 50 Hz

 

EXTRACTION OR VENTILATION SYSTEM

 

If you use the flow visualization Module (AFM 17), you must connect the air exhaust to a suitable air extractor, window or ventilation system.

 

COMPRESSED CARBON DIOXIDE


For the flow visualization Module (AFM 17), you must fill its gas bottle with compressed carbon dioxide.
