Engine 3F Efficiency Analysis part 2

Continuing with the analysis of where the input power (heat) to the engine goes, the next item to consider is the conduction loss often referred to as thermal shorting. Conduction losses A Stirling engine of gamma configuration, such as the one being considered, uses a displacer to shuttle the operating gas back and forth between […]

Engine 3F Efficiency Analysis part 1

In an earlier post I measured 1.05 watts output from my engine 3F using a 69 watt input. This computes to 1.5% efficiency. So where did the other 68 watts go? The following is my analysis of where all the energy went. It won’t be as rigorous as I would like, partly due to lack […]
