文摘
- •
A bond graph dynamic model of the Ericsson engine expansion cylinder is presented.
- •
Dynamic aspects are modelled: pressure drops, friction losses, wall heat transfer.
- •
Influent factors and phenomena on the engine performances are investigated.
- •
Expansion cycles close to the theoretical Joule cycle maximize the performances.
- •
The heat transfer at the expansion chamber wall reduces the performances.
