Hear two vane rotors are connected by regenorators in the rotating hub. This gives a four alpha stirling configuration. the conections between sectors need to be established for this to work properly.
Yes, the drawing should be precised for the conections.
To increse the amount of heat that can be transfered a sprayed liquid would be used . The heat transfer in a stirling is proportional to the surface area. incresing the size of the engine gives gas volume cubed and surface area squared . this means small engine are usualy more efficent . With liquid spray this means any size engine will have the same efficency.
Exactly, I add that for the hot side, one has to insulate it because there are thermal losses by conduction and radiation.
This form of rotary stirling is diffrent from SPRATL in that the regenorators are conventional forward/reverse flow instead of the HX tubes you use.
Right, you've well thought about it. I think that continuous and unidirectionnal flowing is better. It makes a nearly perfect thermal exchanger, and thus a very good regenerator.
I thought you would like to see a conventional representation of rotary stirlings.
Thanks, indeed there are not a lot of rotary Stirling engines. This one one with rotary blades is interesting.
Bye !
), altough I've well seen your picture.
