Examination of Stirling engine parameters effect on its thermal efficiency using PROSA software

This paper uses second-order software for evaluating five Stirling engine parameter?s effect on its performance to select an appropriate configuration with optimal dimensions use in a concentrated solar power plant. Appropriate configuration, heater shape, bundle tube heat exchanger size, and regenerator type geometry are studied. Results show that Alpha is the most suitable high-temperature differences, U-shaped tubes advantageous combining good efficiency fewer pressure losses. Shortening inner diameter increasing number strategy increase also length generates reduction efficiency. Regarding regenerator, wire mesh presents compromise between minimum drop losses provides better For obtained thicker mesh.
