I sincerely apologize to the group for this message. The information given to me on the application to join looked really good but the reality was quite...
I am contemplating a new configuration of stirling engine in an effort to obtain compression ratios only available to the alpha configuration while retaining...
it would be useful for everyone posting about efficiency to make the distinction between thermodynamic efficiency, and what i choose to call engineering...
A photograph of Franchot's 4-cylinder engine from his 1853 patent application is shown on page 21 of Hargreave's The Phillips Stirling Engine. All of the cold...
It is customary on this group to speak of efficiency as the total overall efficiency of the mechanism. I believe you call this "engineering efficiency" I...
the water is a cool idea. G Walker discusses that in one of his books. The water makes sealing easier and yet has a low molecular weight so if it floats around...
I was wondering if there was a good group on making gas filters. Or some web pages or something. What I am looking at is filtering Nitrogen or Helium out of...
Ravi, Are you SURE we are talking beta configuration? I ask because most beta engines use the SAME cylinder for both the displacer and power cylinder. The...
Hello... Rick I have question's for you but all private email for you are rejected. Can you check that or send me another emai address? Thanks... Slavko....
various membranes are available for gas separation, but they are not something you can whip up under the old elm tree. there are also machines that are called...
... Thanx for your reply. I have built a model with a displacer cyl connected to a smaller power cylinder and a diaphragm. I would like to now start upgrading...
Hello I'm new to the group, I'd been researching about stirling engines for half a year. In the last weeks, I started to study the basic thermodynamics...
SESUSA, I've noticed conflicting issues in the different simplistic HX (Heat Exchange) models I've tossed around. The simplest model of HX is that its...
I agree that in the design of a heat exchanger for a Stirling machine that it is important to consider the heat transfer area and the pumping loss. If these...
Twice the channels doesn't give half the pressure drop. It gives .707 times the pressure drop, assuming that you are in the same fully turbulent flow regime....
Guys, Thank you for your replies. In the beginning of chapter 5 of Hargreaves, he writes: "Under certain circumstances it is possible with this arrangement to ...
maniacal engineer, all, Is your analysis disclosed or proprietary? Perhaps you could add the analysis' that you might have to the files section, so some of us...
I think you may have taken the simplistic beyond the edge of reality (i.e. the Beale equation is simple but inaccurate). The channels page is a conversion from...

I give the equations in post 7092 as: ******************************************* Because that is what the math says. L/N = D^4 *(pi*rho*dP*Gc/(128* mdot*myu))...
Hi Well I've been designing a beta stirling engine, taking lots of ideal considarations. The drawings are wating the approval form the moderator. The album is...
Hi Alex, Sorry no one responded to your first message. I forgot about it. Are you working in mks units? Meters, kilograms, seconds? I'm a Matlab user. I'm...
Tom, all, I studied the "Tube_chan" page in GCS. IMHO, "Slot_chan" would be a more descriptive name. The "Width/Depth" heading is mislabeled, it should be...
MP, I agree with your assesment. Tom ... be "Depth/Width". ... definition ... simply ... the ... design. ... in ... generally ... HX. ... stacks. ... ...
Tom, list, One can actually take this much further. The D/W ratio is not independent of the other design parameters, so I think it makes more sense to...
Ummmm.......... not quite. The rh is taken from the calculation done by the GCS. rh is one of the ratios scaled from the prototype and the resulting value...
