ABSTRACT:
Objectives for the study are to demonstrate future kinematic Stirling engine design, performance and production cost.
The concept evaluation shows that the four cylinder double acting U-type Stirling engine with annular regenerators is the most suitable engine type for the 15kW solar
Further improved components show an impact on efficiency of the future metallic engine to 45%. Increase of heater temperature, through the introduction of ceramic components, contribute the greatest amount to achieve high efficiency goals. Future ceramic Stirling engines for solar applications show an efficiency of around 50%.
