The Hilton Airflow System F100 and its expandable range of optional accessories enable students to safely investigate the fundamentals of airflow and simple aerodynamic experimental procedures. The unit consists of a small footprint, high volume high pressure centrifugal fan with adjustable flow control, inlet and outlet couplings. The Hilton Airflow System F100 is available with an extensive range of optional accessories that makes the unit a very flexible and economic investment. The extensive range of optional accessories allow investigation of Bernoulli’s equation, drag forces on various shapes, Investigation of a turbulent jet, investigation of boundary layer development, pressure distribution of flow around a bend, fan performance characteristics, jet attachment, pressure distribution around a cylinder, pressure distribution around an aerofoil, flow visualisation studies, air flow measurement methods.
The complete range is safe and suitable for unsupervised student operation and responds immediately to system changes allowing efficient use of laboratory time.
A round parallel tube with a sharp edged discharge is used to create a turbulent jet using the air from the Air flow System F100.
A 90 degree bend of constant cross section has air blown through it from the Airflow System F100. Along the inner and outer radius at strategic points, static pressure tapping points are located.
A rectangular slit directs an air jet towards a Y shaped duct with two outlet passages.
The shape of the duct may be changed by tilting and sliding moveable elements to allow students to investigate the Coanda effect of jet attachment to a wall.
By blowing air from one side or another at the jet, the airflow can be directed down either of the Y shaped passages as in a pneumatic flip-flop.
A short duct with integral load balance allows the drag of a body to be directly measured at a range of approach velocities.
The bodies include an aerofoil, cylinder and plate.
The cylinder has a radial tapping to allow investigation of the pressure distribution around the cylinder.
A smoke generator generates a visual oil mist that is introduced into the airstream ahead of the test shape through a number of fine nozzles.
The resulting smoke filaments clearly show streamlines around the test shapes.
