SUMMARY

The discussion centers on the efficiency comparison between a one-moving-part Rankine engine and a Stirling engine. Participants assert that a single-moving-part Rankine engine can outperform a Stirling engine, although the claim lacks mathematical proof. The conversation emphasizes the necessity of quantitative analysis to substantiate such assertions, highlighting the importance of established research in the field.

PREREQUISITES
  • Understanding of thermodynamic cycles, specifically Rankine and Stirling cycles.
  • Familiarity with engine efficiency metrics and performance evaluation.
  • Basic knowledge of mathematical modeling in engineering.
  • Research skills to access and interpret scientific literature on engine performance.
NEXT STEPS
  • Investigate the thermodynamic principles governing Rankine and Stirling engines.
  • Learn about the mathematical modeling techniques used to analyze engine efficiency.
  • Review existing literature on comparative studies of Rankine and Stirling engines.
  • Explore case studies demonstrating practical applications of single-moving-part engines.
USEFUL FOR

Engineers, researchers, and students interested in thermodynamics, particularly those focused on engine design and efficiency optimization.

Can a one-moving-part Rankine engine be more efficient than a Stirling engine?

Welcome to PF.

What has your research so far indicated?
 
My research indicates that a single-moving-part Rankine can out perform a Stirling but I don't have the math to prove it ... :-(

The "math to prove it" would depend on numerous factors. What do you think those might be? Under what circumstances "can" it happen?

Which appears to mean your personal attempts to wave your hands.

Have you looked at the literature to see if any professionals in the field have investigated this topic, and if so, what they found?

Without math you're just waving your hands. That's not a good way to investigate a scientific question.
