Thermo acoustic engine 1

[Sojournerman]

Hi everyone was wondering if anyone out there has some good info on TAEs (thermo acoustic engines ) Done the Google and YouTube thing and found a few good articles but none that really give dimensional info on how to make a good basic engine got a couple​ of fairly good pictures from Google image search
I guess what I want is the proportions (i.e) stack length to resonator length​ to piston size etc . I guess I want the proportions so if I decide to go bigger it would be easy to model and make
Thanks for any and all help and advice
I am building test tube version firt so I can learn what's going on and then going to enlarge it. Thanks
