If I remember correctly, SES bought the engineering company WGA which was a couple of very experienced mechanical engineers with extensive experience in dish...

list, On p.159 of "R & SE" -Organ, I find this: Organ's empirical curve fit to real engine data: rpm = 14.16 * SQRT(((Rgas)(Tref)) / (Lref)) Incidentally, the...
MP, I'm sorry but I don't know exactly what you are referring to. Could you explain what you mean a bit further and perhaps point me to the sheet/cells that...
Tom, list, ... Then solved for w (omega), the angular frequency of the cycle. w = (Nma/ Lref) *SQRT(((Rgas)(Tref))) f = w/(2 pi) and rpm = 60 f so, rpm = 60 w...
MP, Well I see what you are doing. BUT, I still do not see why you are doing it. Two of the basic parameters of Vsw, Pressure, RPM, and Gas are set by the...
Tom, Okay suppose you're designing an engine, and you enter some arbitrary values for swept volume, mean pressure and gas type. What value do you enter for...
Tom, I hope I wasn't getting too "testy" there, sorry about that if I was. I'm trying to read Organ, (starting with the words! :-) ...I'll see what I can find...
MP, I wrote a multi page reply but then I couln't get my computer to post it. So here is the short version. 1.] The GCS is to estimate the form the heat...
MP, The GCS is for calculating the HEAT EXCHANGER geometry. It is not a simulator. If you enter swept volume, mean pressure and gas type that is all that is...

Say I have 2 hypothetical engines. One is IC; one is stirling. I know the output of the IC engine (it says on the side) and I want to know roughly how much the...
You are comparing apples and coconuts. Can't happen. Tom ... From: danielskorupka To: sesusa@yahoogroups.com Sent: Saturday, March 01, 2008 6:10 PM Subject:...
Yes, but is that equation reasonably valid? "Power in watts= (2x pressure x > absolute temperature ratio x compression ratio x cross-sectional area of power...
no they are not valid. the constraints given indicate a dearth of Stirling understanding. I recommend reading a great deal more before more posts. Tom ... ...

Hi Tom, Thanks for the long and thorough reply. In general, I agree with you on the function Organ's scaling method/GCS provides, and the role it plays now...

list, To correct myself on what I said last time about the Beale and West numbers, apparently they don't change much with gas type, because the change in power...
I didn't know we were debating. I thought I was telling you how it is. Since I wrote the GCS, I have a rather patronistic attitude about how it works. I don't...
Nick, I think you missed the Stirling here! It is transparent, so that's partly understandable. It';s an example of the very-low delta- T engines originally...
Pardon my attitude, but why are most Stirlings made real small? Are there no engines that can power a 20KW generator available in plan form on the Internet? ...
There are about the same number as the IC generators of that size. 0 ... From: Hal Davison To: sesusa@yahoogroups.com Sent: Monday, March 10, 2008 1:45 AM ...
Hal, Commercial 20 kW Stirlings seem to cost more than people want to put out for free on the internet. ($5,000-$10,000/kWe?) I have seen the 35 kWe and 85 kWe...
