Stirling Engine D

The Stirling Engine D is a functional model of a Stirling engine based on an idea by Professor Wilcke and is optimised for the demonstration thermal to mechanical energy conversion. Clearly displaying the the operation of a thermal engine, the apparatus is perfectly suited to investigations of the Stirling cycle.

The interplay between the displacement piston and the power piston can be seen especially clearly at a low rate of rotation. In this version the displacement piston moves discontinuously, with a dwell time during the heating of the working medium (air) and a second dwell time during its cooling. This offers a clearer demonstration of the ideal Stirling cycle than is possible with continuous piston movement.

Adjustable to operate with a variety of heat sources, the Engine can be heated by its integrated hotplate, a candle flame or focused radiation from the sun or a lamp. 

For recording pV diagrams, the pressure can be measured via a rubber hose connection on the power cylinder, and the volume can be measured by attaching a thread to the power piston to follow its movement.

Experiment Topics:

• Operation of a Stirling engine as a classical heat-engine
• Measurement of the no-load (idling) rate of rotation as a function of the heat input
• Recording and evaluating a pV diagram

Advantages

• Slow running allows for the interaction between the displacement piston and the working piston to be observed easily
• Discontinuous motion of the piston provides for almost perfect p-V (pressure-volume) diagrams
• It is possible for the system to be heated by absorption of radiant heat
