dimensions for displacer on a Stirling engine?
I want to make a low temperature Stirling engine. I was looking at some different designs for them and none really have a set dimension for the displacer. All the ones I see must just be guesswork. I have a glass tube that I was going to use for the power cylinder about 16mm diameter I will build it like this.
I have no idea what size the displacer cylinder and displacer will need to be for it to be effective. can anyone guess for me?
I also need to know how much the piston should move for it to be effective.
