HI,
I am going on a design of a gamma type Stirling engine, here i would
like to ask about the design of the end side of displacer cylinder
(hot side - expansion space). I have been referred to several books
that they had suggested the use of dome shape for it. If i am going
to construct a rounded-flat shape of the end cylinder (with a small
radius fillet corner), can it work? my hold temperature is around
600 celcius. the material used is Stainless steel with thickness of
5mm.
thanks

Shape of the hot side of Displacer Cylinder
The books are relating the experience of those have designed and built Stirling engines as a part of their job. I would accept their advice and do likewise. The hot end of the displacer is exposed to the high temperatures and it as will as the end of the hot cylinder must fit closely together as well as withstand the pressures at the high temperature of operation. A flat cylinder/displacer would distort and possibly destroy that portion of the engine.
