List, I have added a JPEG and MPG file of the Twin Gamma Stirling (TGS) design I have been working on to the files section folder "Rick Topf's Designs". I am...
Javier, Strictly speaking these were Air Engines and not Stirling engines. The name Stirling Engine was given to engines from Philips Laboratories in April...
I would like to first thank you for allowing me membership to your group. I should first introduce myself, my name is Shawn Galloway. Currently I am working...
thank you for the introduction, interesting my brother served as security at SAC HQ for a number of years, now he's a cornhusker fan living in NC. but...
The use of carbon Aero gels has crossed my mind but a little hard to manufacture. Using carbon Dioxide under super fluid condition around 1000psi 32 degrees C ...
Tom, While it is true that the adoption of 'Stirling engine' as generic term dates only from the Philips era, an earlier attempt to introduce it was made by...
Rather expensive but very worthwhile. Introduces a starting point for a WWW based 'group' design of a nominal 1hp air (or nitrogen) charged engine, the...
Nick, This may be a controversial statement but I believe that requiring the use of air/N2 is driving a square peg into a round hole. The same results can be...
As I read the AOJ Article #1, it didn't seem that he was promoting N2 in favor of He rather that he was discussing the factors and the math using 2 similar...
How can that be? We are using the factors he chose to use in the case of Similarity/Scaling. Tom ... From: Tom Carey To: sesusa@yahoogroups.com Sent: Tuesday,...
CW, "Check it out and see what you think after looking over the Rice University info." I would like to look over the Rice U. info, but you did not provide any...
No, I don't fully understand AJO's concentration on air charged engines. But, given his track record, I am willing to accept that the lack of understanding is...
I was referring to his Article #1 about regenerator design. In particular the following sentences. A limitation on the rpm of the air- (or N2-) charged engine...
I've moved a full PDF study file to the group files under the CW folder for your review. Just a couple of notes which caught our attention, 1) the thermal...
I agree with all you say now except that for He and H2 mechanical inertia is the limiting factor in RPM and thus Ma. (I went back and finished reading the book...
A quick read of this pdf indicates that it is off topic. Since you and Rick were talking about it I will leave it for a week for Rick to read and then remove...
In the past there have been various projects that have used encapsulated phase change materials (PCMs) to achieve some sort of heat transfer advantage. These...
SESUSA list. In googling for Heron's Fountain for my grandson <MotionMountain.net> was listed as a source of information. Haven't found Heron's Fountain yet...
So why does AJO concentrate on air (N2) charged engines where the complications of compressible flow occur within the mechanical limits, rather than light...
You probably need to address this question to AOJ. My take is that he is making the point that the generally accepted method of engineering is based upon a...
You are probably right. I have corresponded with AJO before and intend to write to him regarding some of the historical aspects of this latest book, so perhaps...
I think you already know the answer to your question. There are some circumstances where the additional requirements of using He or H2 are not worth the...
Although these emails are probably off topic as a subject, as a philosophy of design it bears commenting on. There are some very good theoretical reasons to...
Tom Your points are well made. I'm going to plead ignorance on a few things here and ask you to help cure that personal problem. So if I ask a few silly...
Well I asked and (with apologies for likely loss of page structure due to my cutting and pasting)got the following pretty full reply:- "Why air? First of all,...
Thank you for sharing his reply. He is pretty clear about his point of view. Tom. ... From: n_highfield To: sesusa@yahoogroups.com Sent: Friday, May 23, 2008...
