HOW A STIRLING GAMMA ENGINE WORKS?
With regenerator
A gamma type Stirling engine with a regenerator is almost without equal, but with the difference that the communication of air between the top and bottom of the piston displacement does not occur because the space between the piston and the corresponding cylinder, it diverts the air to force the passage of this through a regenerator when communicating with hot cold focus. So do not leave any space (or very little) between the piston and the cylinder displacement.
Phases of operation of this engine is practically identical to a Stirling engine regenerator without end, but this model has advantages and improves the performance of the machine.
The regenerator is usually a metal mesh able to retain energy as heat. The fact that I can store some energy for the cycle occurs more easily (from a few repetitions)
- During the early stages, when the hot air fills the cylinder, passes through the regenerator. Because the focus was cold, does not transmit (or even picks in the first round) any heat. The air, the hot center was heated up almost everything has already passed this part hotter. When the piston starts moving down and forces the air to rise again towards the cold source, it passes through the regenerator, heating it. This means that the temperature increase and therefore some energy storages.
- When it restarts the cycle of displacement and piston begins to rise again, the focus cold air passes through the hot regenerator. Since it already had some stored energy transmitted in the form of heat and gas when the quest gets hot center, already has a very high temperature and it costs less heat up. So get optimize Stirling cycle. When the air turns cold to go to the center again, again leaving the regenerative energy and helps focus the cold gas reaches a lower temperature, thereby also the cycle.
During this cyclical process, the regenerator always acts in favor, we always emphasize the temperature difference between the hot and cold sources.
Regenerator helps the energy required for the process to occur is lower because it can store a portion, allowing less heat is needed to heat the gas in the hot center and less time to dissipate the cold heat source.
