Dear all

I have some questions about GPU-3 stirling engine .... please help me

How I can calculated free flow area and wetted area for heater, cooler and regenrator for GPU-3 stirling engine?

or

Are there a fixed value for free flow area and wetted area for heater, cooler and regenrator for GPU-3 stirling engine?

When I calculated the mass leakage to crank case due to leakage effect. it need some variable....
gas temperature  ... what is the value of it
piston length ... what is mean by it
piston linear velocity ... how i can calculatee?

regards

Hi,

you can find the Stirling engine design manual free on the internet (as pdf I think).

It has very detailed data of the GPU-3.

Greetings

Thanks Ralf
yes I found it
but what I need does not found in it, so there is a relation to calculate the free flow area and wetted area, but I can't find it
