Hello everyone,
I think I understand that Tomsid has imagined a STIRLING "double paddle module" and wishes our opinion ....
WELL :
I am not a specialist in STIRLING machines but I think that during the volumetry cycle, the smaller the minimum volumes (or even zero) the better: it is CARNOT which imposes its laws?
What do you think Robert SYCOMOREEN ....
"and for Tomsid: if you are english ... write in english, you are on an international forum between the CANADA and the CHINA "

Hi
I have trouble navigating this list as i do not read any french, sorry.
The picture represents my current thinking on rotary stirling engines
Hear two vane rotors are connected by regenorators in the rotating hub. This gives a four alpha stirling configuration. the connections between sectors need to be established for this to work properly.
To increse the amount of heat that can be transferreded to 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 efficient. With liquid spray this means any size engine will have the same efficency.
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.
I thought you would like to see a conventional representation of rotary stirlings.
hope this is of interest
yours tomsid
[quote = "Remundo"] Hi Pascal, Hi Tomsid,
I don't know your country and your language, I don't understand well your question (as there was no question: D), altough I've well seen your picture.
It would be a hot air engine ...
There is no problem to speak in English.
Read you soon, bye! [/ Quote]

Yes, the drawing should be specified for the connections.

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.

Thanks, indeed there are not a lot of rotary Stirling engines. This one with rotary blades is interesting.
Bye!

ZZ machines in STIRLING
Hello Raymond,
I browsed your SYCOMOREEN site and you talk about SPRATL again: thank you, that's good!
But hey hey ....: "the new concept ZZ" in STIRLING fashion especially the ZZ 1 C and ZZ 2 ... that would be great right?
Imagine a thermo dynazmic set within which the 3 D sphero-kinematic concept of the ZZ merges with the thermo dynamic concept of our dear Scottish pastor Robert STIRLING ..... this would give birth to amazing rotary machines unique in the world, a must of technology right?

Here we are: January 7!
hello: Happy RAYMOND Celebration!
with the question for a champion:
Do you think that the successful concept of TTVR by Jean Claude could be taken "cinematically" for an adaptation of the functioning in STIRLING mode?
Ha?
