The discussion centers on the efficiency comparison between a one-moving-part Rankine engine and a Stirling engine. One participant claims that their research suggests the Rankine engine could outperform the Stirling engine but lacks mathematical proof to support this assertion. The conversation highlights the importance of mathematical validation in scientific claims, emphasizing that without it, the argument lacks credibility. Participants stress the need to consult existing literature and professional studies to substantiate claims about engine efficiency. Overall, the debate underscores the necessity of rigorous analysis in evaluating engine performance.

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?

My research
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.
 

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
