Hello, Michael, I have sent some details of the photos to Dusty to add to my web page, I guess you have seen them by now. The best running power over a period...
Hello Harry, Thanks so much for the details and insight from your Stirling engine experience. We rarely hear details, especially failures. We all learn from...
Harry and Elaine: Thanks so much for the comments. They provide a lot of insite into the process. I haven't been back to the photos yet but I'll definitely...
Attention expert scrappers, I was wondering if anyone has tried using the tubing from a hydraulic "bottle" jack for reuse as cylinders for a Stirling engine. ...
I am not sure what the condition of the inside wall is, but there is 304 ss tubing avail from onlinemetals.com. 2" tubing with .065 wall is $37.67 for a six ft...
James, How are you dealing with the coefficient of expansion with the differnt materials. Won't the graphite sleeve crack when the aluminum gets hot? Same with...
Haven't posted here for ages but some of you may be interested in the 'All hot air' album on my webshots page:- http://community.webshots.com/user/n_highfield ...
Hi Nick, I got a copy of Andy's book with deatils on the 35cc. He says that around 50 kits were sold for this design, perhaps this was one of those, or a...
Thanks for your comments Rick. I too have a copy of Andy's book and, assuming the general assy dwg of the 35cc is to scale this engine shares many of its...
Has anyone examined the use of Phenolic in a stirling engine. Phenolic is used for handles on pots and pans, rocket building and airframes, electrical...
I looked back in the archives at your design but I must admit I don't quite 'get' it. At the risk of being accused of polluting this group with a mere hot air...
James, I have looked at phenolics and many other plastics for engines. Phenolic thermoset resins lose their strength with increasing temperature. They will...
Dear All, I just joined the group and I'm currently interested in developing a Stirling engine to produce electricity for my house (5 to 10 kW). I plan to use...
OOoooooops, Apparently the similarities are all external. My bad. I "assumed" that each "barrel" or the one cylinder had a displacer, hot and cold side as in...
It's just a Beta configuration engine with the power piston moved to the hot end on the probably spurious basis that the expanding air would be better able to...
hi to all group mates, i m doing my study project on stirling engine and i had calculated parameters of the stirling engine by using stirling cycle and some...
hello, I am new to this group and to stirling engines, I've done some background research on stirlings and understand the basics of how they work. My...
Hello Michael, The reason you don't see specific figures is because of the complexity of the regenerator. There are far too many factors that affect the ...
Thanks for the informative response, I guess my question now is how good is the best regenerator compared to an ideal regenerator...40%,50%,60%.. for either a...
Michael There is more to consider than just heat transfer in the regenerator. Adding a regenerator adds dead volume (volume that is not swept by the piston)....
Hello Michael Bloom, The regenerator is indeed a fascinating component of a Stirling. I can only speak from my own experience which follows the work of Andy...
wow, thanks, this is the type of info I have been looking for. I took a look at your website and your engine and description are really good. This should...
Hello Michael, Sorry, I made a mistake in the title of the book. Its real title is Making Stirling Engines by Andy Ross. It was and probably still is...
Superb real world information! I have some really fine stainless mesh (actually more like fabric) and am minded to try it in place of the copper in my recently...
I think the figure you are after is the 'temperature recovery ratio' which is the temperature change of the working gas across the regenerator divided by the...
Do any of the group engineering people know where to find some sort of chart that gives the temperature recovery ratios of different materials. For instance...
