Stirling engine displacer design? Answered
I am designing a gamma Stirling engine (this type) and I am unsure how long the piston should be and how long its stroke length should be the specs for the cylinder and piston pipes are below.
The pipe for the cylinder is stainless steel.
Wall thickness: 1.56mm
Outer diameter: 31.7mm
Inner diameter: 28.6
Length: 200mm (can be cut smaller)
(Stainless steel cap will be welded to one end, the other end where the shaft comes out will be plugged with this nylon/graphite stuff)
The pipe for the displacer piston is aluminium pipe.
Wall thickness: 1mm
Outer diameter: 27.88mm
Inner diameter: 25.88mm
(Two aluminium plugs will be used to seal its ends)
How long should the piston, cylinder and stroke lengths be based on the specs?
