Re: the volume ratio between displacer cylinder and power cylinder

Thanks Ian for your reply,

i understand that there will not be enough hot air to the power cylinder if it has a bigger volume and it is logical btw, but do you have a mathematical proof or a heat transfer derivation for example you can send me to prove it?

the volume ratio between displacer cylinder and power cylinder

Hello, I'm doing a research on the gamma type Stirling and i found that the volume ratio between the displacer cylinder and the power cylinder should be in the range from 1.5 to 2. may i ask why is this the optimum ratio? and what will happen if the displacer cylinder volume became smaller than the ...
