Stirling Cycle Hot Air Engine: Horizontal Cylinders
The unit is for demonstration of stirling cycle hot air engine.
The engine consists of two cylinders. The first (displacer) cylinder is made of Pyrex glass and is to generate hot air by a resistance heater. The second (power) cylinder is to generate a mechanical power on a fly wheel by hot air from the first cylinder. Air flow passage and phase angle between the two cylinders are such that the expanded cool air from the second cylinder is returned for heating in the first cylinder. The power to the heater can be varied. Cylinder ports allow engine to operate on gasses other than air. Instruments are provided for measurement of input power, and output power.
Instruction manual is also included.

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.
TYPICAL EXPERIMENTS- Pressure and velocity measurement.
- Estimation of drag coefficients of various bodies, e.g. sphere, hemisphere, disc, plate, streamlined shape etc.
- Estimation of drag lift and pitching coefficients of an aerofoil.
- Pressure distribution around an aerofoil or a cylinder.
- Effects of instability of a “flutter Wing”.
- Investigation of boundary layer at a flat plate by measuring total head distribution.
- Stream lines visualization using a smoke generator.
- Wakes behind models.

Air Flow and ThermodynamicsMP 330D Subsonic Wind Tunnel: Downstream Fan
This subsonic wind tunnel is an open circuit down stream fan type designed for studying the subsonic aerodynamics. It is to be used with optional accessories and models below.
The air enters the tunnel via an entrance flare. A flow straightener, three wire mesh screens, and a high contraction ratio section ensure uniform velocity across the transparent test section. Downstream of the working section is a low angle diffuser which terminates at the tunnel fan. The diffuser and contraction sections have a high quality internal finish to minimize the boundary layer effects. The fan impeller blades are of an aerofoil design cast aluminum to ensure maximum aerodynamic efficiency and minimum turbulence. Fan speed is adjustable by an inverter.
Four equally spaced static pressure taps are connected to a manifold to minimize effects from a model. Air speed is indicated by an inclined manometer and a calibration graph.
