Re: Carnot engine

Hello friends, to translate from french, you can use this link: http://fr.babelfish.yahoo.com/ Bonjour Serge, Le rendement du cycle de Carnot est-il vraiment insurpassable ? Voici ce que sont mes réflexions sur le sujet. Dans le document "Research on New Isochoric Process" http://www.monot...

Re: A new Stirling engine concept ?

you are just introducing a less efficient one,, the counterflow heat exchanger is THE most efficient heat exchanger. You say replace the regenerator with the heat exchanger, you are not replacing the regenerator, Stirling engines need two heat exchangers: one connected to the hot source and one con...

Re: A new Stirling engine concept ?

It depends on who your peers are. Ian S C SECRETARIES, ADVISORY COMMITTEE and TECHNICAL COMMITTEE: http://www.icreu2012.com/upload/files/ICREU2012-BROCHURE.pdf By now you should give the "new Stirling concept" a rest on this forum as your reviewed paper doesn't apply to our subject matter...

Can't you read: "peer reviewed"
Can't you understand what this mean?

People with a brain can read this paper:

Re: A new Stirling engine concept ?

Lucien01, I fear you are waisting your time on theory, if you do not prove the theory by building a prototype, then proving its performance by instrument readings. Theory is useless without practical aplication, look at all the perpetual motion attempts, you haven'ke t seen one of them work, even t...

Open cycle new Stirling Engine concept ?

A strange compressor at constant volume: "A device has been presented which uses the thermal energy of a hot source. At constant volume, it allows the molecule concentration of a gaseous fluid to increase without spending mechanical energy. It can produce a significant temperature increase abov...

Yes, two images (of the heat pump). I was speaking "heat pump" (this is a first step, I think the most interesting). http://www.hostingpics.net/viewer.php?id=366201Heatpump1.jpg http://www.hostingpics.net/viewer.php?id=652291Heatpump2.jpg Cold side, we have three heat exchanger E1 (Tc-), E...

Re: A new Stirling engine concept ?

Hello Jester, Without mass flow, no power. If the useful mass flow is 100% then the secondary deltaT will be reduced from 130 to 65k. If the useful mass flow is 60% then the secondary deltaT (cold side) will be reduced from 130 to 91k. The cold side is full. The pressure is minimum. 30% of the heliu...

Re: A new Stirling engine concept ?

What Mercier points out is that subsequent slugs of air passing through the regenerator will be expanded by that temperature rise, thereby compressing the air already in A, which will cause it to be adiabatically heated above Th, to Th+. Note that the air in B will be equally compressed so its temp...

Re: A new Stirling engine concept ?

Nobody seems to understand that, FIRST, we have a Maxwell's demon! The heat pump have NO power piston ! Please, try to answer THESE questions: 1- Do you think that a Th+ (a higher temperature than the hot source) and a Tc- (a lower temperature than the cold sink) can "appear" ? (without sp...

hello jacket,

Very clever. Well done!

I'd like to know exactly how it works.

Dear Longboy, How do you feel now? I hope you are going well. If you need some help, send me a PM. Regards, Lucien01 Hello Ferraccio, Do you think this is correct or wrong (from the "heat pump" document): """a cluster of molecules leaves the hot compartment and its temperatu...

Re: A new Stirling engine concept ?

Hello Ferraccio, We know exactly what is happening in this heat pump. The principle is soooo... simple, soooo... easy to understand. Even a young studient can understand it (with clear explanations). A small cluster of molecules leaves the cold compartment, raises its temperature by passing through ...
