Sterling cycle• The idealized Sterling cycle consists of four thermodynamic processes acting
on the working fluid:1. Isothermal Expansion.
absorbing heat from the hot source.2. Constant-Volume (isochoric) heat-removal.
The gas is passed through the regenerator, where it cools transferring heat to the regenerator for use in the next cycle.
3. Isothermal Compression. The compression space and associated heat
exchanger are maintained at a constant low temperature so the gas undergoes near-isothermal compression rejecting heat to the cold sink
4. Constant-Volume (isochoric) heat-addition. The gas passes back through the regenerator where it
recovers much of the heat transferred in 2, heating up on its way to the expansion space.

Selection of sterling engine construction
A Sterling engine is a heat engine
external combustion engine,
cyclic compression and expansion of air
Can be used as prime mover
Low differential temperature requirements

Alpha type sterling engine
Alpha type Sterling engine.
There are two cylinders.
The expansion cylinder (red) is maintained at a high temperature
the compression cylinder (blue) is cooled.
The passage between the two cylinders contains the regenerator

Beta type sterling engineBeta Type Sterling Engine.
There is only one cylinder, hot at one end and cold at the other.
A loose fitting displacer shunts the air between the hot and cold ends of the cylinder.
A power piston at the end of the cylinder drives the flywheel
