DIY Thermoacoustic Stirling Engine

[@adriaanvantulpenbaarduitku7888]

So this one has only one piston, Please explain it to me, don't Stirling engines have two pistons, one displacer piston, and one power piston on the cool site? Thanks.

[@ramneeksingh442]

this is a beta type Stirling engine which has one piston and an air displacer in the tube to help cool air, and when the piston moves the displacer also has movement

[@jimjamse2879]

I think you only need one but it will stall at low rpms

[@DM-kl4em]

I love it when the person foregoes any explanation of the process, and instead plays some loud, obnoxious, earsplitting, and annoying synth music.

[@countinhosuarez8891]

Good day Sir! A question How does this thermoacoustic Stirling engine is different from a Beta-Stirling engine? It's for a project of mine, would appreciate your comments on this

[@TaserFish-qn2xy]

A stirling engine works by expanding when the gas is hot and compressing when the gas is cold. Traditional Stirling have a displacement piston for moving the air to the cold side before compression and to the hot side before expansion. This doesn't have a displacer ! So how does it work ? The key is the steel wool at the end (I think). It acts as a regenerator. One side is pretty cold, the one near the flame is hot. So when the piston moves left in compression, the gas moves further into the regenerator and cools down, which aids the compression. The opposite happens when the piston moves right and the gas expands out of the regenrator. It leaves the hot end and aides the expansion. But I suspect this is a little finnicky to get to work and the video may be fake.

[@artupaysivar6884]

​@@TaserFish-qn2xyi get the concept when piston moves left it is cooling down the regenerator, but im confused on why does it turn left and not just stay at right since the hot air pressure pushes the piston to the right?

[@artupaysivar6884]

​@@TaserFish-qn2xyalso, can the syringe tube and piston (corkscrew) parts be replaced with metal? i know that heat will distribute faster but maybe i can create a bridge between the heated parts and the piston using wood or such to establish heat difference, had a school project involving metal and 3d printing and i want to build this

[@TaserFish-qn2xy]

@@artupaysivar6884 A few things make it keep spinning. 1. There is a flywheel/ rotating weight. Even if the hot air pressure keeps pushing to the right, the flywheel still has momentum and squishes the air back together. 2. As hot air gets pushed into the (relatively) colder regenerator, it cools and contracts, effectively "pulling" the piston.

[@TaserFish-qn2xy]

@@artupaysivar6884 Well, it has to run smoothly and be mostly airtight. That's not a easy. In fact, this whole process quite finnicky. The size of the hole and amount of steel wool will also likely have to be tuned/ experimented with until it works. I'm not sure that metal on metal will run smooth enough and with small enough tolerances to make it work. Guess it depends how well it prints. And the syringe part being metal is really making it harder. The regenerator should be much colder on one side than on the other. If it's all in a metal cylinder, then that doesn't work. Mayyyyyybe you could make it work but I really don't recommend it. For such a simple project this is more than hard enough to get working without the metal. You're probably better off doing a typical Stirling engine with two pistons and two cylinders if you're working with metal. Alpha type for example. The benefit there is that the hot and cold side are separated. If it's all in the same metal cylinder it's harder to get a decent temperature difference. That is if you can actually make the pistons run smoothly and close enough to airtight. I'm not an expert, but I've wanted to build a Stirling engine for a while and I've got the theoretical background on it. Lemme know if I can help some more.

[@MikeConner.akaRadio]

What is the material the piston is made from? It looks like carbon maybe, but I can't tell in the video. Does anyone know what it is? Other than that sure seems very elementary to make, and I'm excited as ever to do something like this with my grandkids. Thank you tons for the inspiration. 😊

Eu já fabriquei um motor semelhante a este em um vídeo que postei em 2018. Mas este motor em especifico do vídeo, não funciona não, isso é fake, primeiro que este modelo de motor com pistão único é muito fraco para rodar esses rolamentos normais que ele usou no vídeo e segundo com a dimensão do motor, jamais iria funcionar usando somente uma única vela como fonte de calor. Fora outras coisas que reparei no vídeo como o próprio pistão em madeira que não se consegue boa vedação que é necessário para um projeto como este.

How does it even work??

Also the energy conversion must be higher or equal to the energy consumption.
