Whaooo, if this little stirling is beautiful! Is that he would give me everything, this beast! Almost as much as a pretty woman glancing at me : Cheesy: !

Well, more seriously, when will the first prototype tests, Raymondo ??? You make us languish, there !!! Even no need to pass the mop, home ...:frown:

The question is also valid for the promising POGDC-Stirling based on SRATL ... : Wink:

Hi Louphil and Pascal,

The SPRATL is not on the agenda.

I am currently focusing on the MPRBC, but I don't have that to do ... Back to school is here and the little aspiring engineers are waiting for me :P

Hello everybody

Some news from SYCOMOREEN's Stirling,

Recall
Image
The TriLobic Annular Pistons Stirling Machines (SPRATL) result from the adaptation by SYCOMOREEN of trilobic RPATL machines prints by Pascal HA PHAM

The design of SPRATL machines is attached to reduce or even eliminate all the faults currently known on Stirling machines, mainly:
1) Volumetric fault at Vmin and Vmax
2) Failure to respect the cold and hot isotherms
3) Fault in caloric regeneration of the fluid flowing through the 2 isochores
4) Spontaneous heat transfer between the cold and hot parts of the machine without working the fluid.
Image

Point 1 is completely deleted

Point 2 is optimized by intense flows in hot and cold machines

Point 3 is optimized by an opposing and continuous flow heat exchanger

Point 4 is optimized by the almost complete separation of the hot and cold parts in the machine as suggested below.
Image

All these improvements will make it possible to "tangential" the ultimate thermodynamic efficiencies of Carnot, as much in engine as in heat pump or refrigerator.

New arrivals
First, he is preparing some prototypes, but it's still a little too early to talk about it.

But there is more interesting ... You are aware that Pascal HA PHAM and Yves SAUGET work in close collaboration on spherical machines ZZ, and forge links with another inventor of spherical machines, Shi Zhe and his Fuhaidangu machine.

The first sketches and reflections allow us to envisage adaptations in Stirling of these spherical machines with the same qualities as the SPRATL design.

I now let Pascal or Yves say a word to you.

Come on let's go!

mastering the cold does not scare us .... neither is the heat elsewhere, for Stirling mode you need both

on two floors ......

now we will have to tame these dream creatures ....

suggest different volumes at the top and bottom!

consider them as fragile young and pretty young ladies

teach them to move together in the same ballet,
on an imaginary dance floor ...

Here is a very brief overview of the spectrum of milling machines, a globally subtle spectrum = there is no shortage of material,

it is breathtaking ... divine to be able to bring it all together here.

"to make STIRLING nectar .... for example"

A + friends

: Cheesy:

See you soon

PS very well if Raymond can translate into English for SHI ZHE!

Pascal HA PHAM wrote:if we want to obtain the greatest possible volumetric difference between the 2 stages, it is the association of one stage in ZZc geometry and the other in FF geometry which provides the greatest differential ... & is this good using the large volume in ZZc and the small in FF?

What then is the first evaluation / approach of the maximum differential coefficient of V = the "CDMV" (½… ..1 / 3… ..less?)

When we use identical geometry on both sides of the machine, how does this "CDMV" evolve for ZZc and for FF?

and yes the friends that specifies .... the 3 musketeers will leave the trump of 20!

Hello Raymond,
uh i'm not sure we're talking about the same thing:

DIFFERENTIATED BI VOLUMETRY:
there is actually a compression ratio at the top and another at the bottom (the 2 may also be identical) but the concept of CDMV is the ratio between the volume of one stage compared to that of the other stage brought down to a cycle.

"and it's not the same thing"

isn't it?
: Cheesy:
Tryphon Tournesphere

The "CDMV" will refer to the compression ratio. It is also called compression rate, more rarely expansion rate.

The volumetric ratio of a thermodynamic cycle characterizes Vmax / Vmin fluid that we make work

To make an optimal Stirling, the dead volumes must be zero, as realized on the SPRATL.

Compared to ZZ machines, this means having the lowest possible dead volumes. As on the SPRATL, the volume ratio will be achieved by the ratio of the maximum volume of a room on one floor to that of a room on the other floor.

Scoop: college to 4?




by Pascal HA PHAM » 22/02/10, 15:02

I announce to you SHI ZHE's wish to be part of our college and also to come and talk about his inventions (FF machine in particular) in our favorite discussions on ECONOLOGY.

His decision and his confidence are exemplary

The language barrier = French / English translation then English Chinese,
and conversely in return messages, however, the flow of trade between China has slowed down and we will endeavor to make this more prompt and more fluid.

We would therefore like to wish this nascent collaboration long life with the SHI ZHE FF concept which integrates admirably with ours and therefore completes an existing catalog of already rich engines and machines.

future joint projects are already in the making.

This openness reveals that well interwoven techniques and phiosophies can cross borders and demonstrate that a new pardigma is possible: this mode of operation immediately reveals multiple unsuspected advantages.

See you soon....
:D

Pascal

INDUCTION OF SHI ZHE and his FF machine concept




by Pascal HA PHAM » 22/02/10, 16:41

Here it is done, SHI ZHE has become the 4th musketeer of our college of inventor, his inventions will now be by our side and the catalog should grow even faster following other college projects!

We just sent him this message:

Good afternoon SHI ZHE,





I am very happy about your answer and I think that Yves and Raymond will be too.



I specify you that the ZZ engine is a collaborative invention between Yves Sauget and me and that the SPRATL (Stirling engine with rotary annular trilobic rotary piston) is an invention of Raymond (SYCOMOREEN) which is based on my original trilobic concept.



When there are strong innovations at the end of the way, We don't hesitate to make our neurons work together and we serioulsy think that there are a lot of new project to build and launch with you.



Could you give us your age and send us a photo of you? It would be a lot more nice.





Through the mail of today, your confidence and your friendship are honoring us.





We are OK to promote your engine in our current websites and forums. It only missed your explicit agreement and it has just been confirmed.



We are going to update our documents progressively by adding your name in our team of inventors (which raises from 3 to 4) and distributing it in the same way.





We think that it is relevant to drive bigger R&D projects about the fraisoidal engines where your Fraisoidal Fuhaidangu (FF) takes a precious role.



Thus we are with you and your country at the beginning of a new international collaboration, notably about Stirling's engines which are finding their characteristics and their performances in the set of our wonderful catalog of new engines.





All this is done while respecting the inventions and individual ideas and with an intense transparency and collaborative mind.



An increased impact of our works and an international recognition of our new team are already seen and known.





We have several patents to write and I think that we will need your skills to create new engines.





Have a great day our new friend,



Pascal HA PHAM

Yves SAUGET
