Air Flow and ThermodynamicsStirling Cycle Hot Air Engine: Vertical Cylinders
The unit is for demonstration of stirling cycle hot air engine principles.
The engine consists of two vertical stainless steel cylinders. The first cylinder is to generate hot air using a heater. Power to the heater can be varied. The second cylinder is to generate a mechanical power using hot air from the first cylinder. Both cylinders are attached to a common shaft, with a suitable flywheel. The hot gas cylinder head is cooled by outside water supply. Instruments are provided for measurement of input power, and output power.
The advantage of this design is the ability to bring the engine to operating condition in a short time.

Air Flow and ThermodynamicsSubsonic Wind Tunnel: Upstream Fan
The wind tunnel is an open circuit upstream fan type, designed for studying the subsonic aerodynamics. It is to be used with optional accessories and models below.
An axial flow fan delivers air through a diffuser, aluminum tube flow straightener, three wire mesh screens and a high contraction ratio section to ensure uniform velocity across the transparent test section. The diffuser and contraction sections have a high quality internal finish to minimize the boundary effects. The fan impeller blades are of an aerofoil design cast aluminum to ensure maximum aerodynamic efficiency and minimum turbulence. The fan speed is adjustable by an inverter.
Four equally spaced static pressure taps are connected to a manifold to minimize effects from a model and air speed is indicated by an inclined manometer and a calibration graph. Models are mounted on two components load cell support with digital display for measurement of drag and lift. Model holder can be rotated to allow quick change on the angle of incidence, this angle is indicated on an angular scale.
The wind tunnel is mounted on a steel table on wheels.
Instruction manual is also included.
