How to make a Thermoacoustic Engine

[@wazza33racer]

the rubber ring to stop the piston over traveling is also the "choke" which is necessary.

What Is Islam? Islam is not just another religion. It is the same message preached by Moses, Jesus and Abraham. Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. It reminds us that since God created us, no one should be worshipped except God alone. It also teaches that God is nothing like a human being or like anything that we can imagine. The concept of God is summarized in the Quran as: { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) Becoming a Muslim is not turning your back to Jesus. Rather it’s going back to the original teachings of Jesus and obeying him

[@Brinta3]

ahmd abdallah Isn’t Islam that religion which instructs you to murder anyone who refuses to agree with you?

[@TMI_CO]

@@Brinta3 the opposite. It's the people who have made it that way, just like any other religion. Imam Ali, a great person in Islam who stood along with the prophet Mohammed actually said that there are only two kinds of people in the world, the brother from your religion, or the brother from your humanity. This means the central character of Islam is equality unbiased on your beliefs.

[@heavycurrent7462]

If you added a constriction between the heated chamber and the piston it will work better. The constriction itself will help with the formation of low pressure region that would pull the piston back in

I have not experimented with different syringes and test tubes, but I think that you can use different ones. Thermoacoustic engines have a feature: less volume - higher frequency / speed, more - vice versa.

[@sharvaparalkar]

country boy why do you add water?

[@Currychicken5]

Sharva Paralkar so one side is colder wich can make it even faster

[@dude-hh9db]

Hmm, this is not a thermoacoustic engine. Because the required phase shift does not originate from gas dynamics (e.g. the gas change at the regenerator is later than the power piston top dead center like in a TASHE engine) but on the fact that the heat transfer from regenerator to the gas is delayed. So it is a thermal lag engine.

Perhaps you `re right.

[@raulglz.4183]

What can I use instead of the syringe?

[@grain-diose]

Don't even try. You will not make such a high-quality piston at home. Even on a good lathe, this is difficult. And from a syringe with Aliexpress you get the perfect piston. You can make a low-temperature Stirling engine of this type completely out of scrap materials - kzbin.info/www/bejne/nYrJo36DnN6Shsk

[@Flederratte]

nice one. I ordered some glass syringes but the first one arrived broken so I have to wait for the others to arrive.

[@grain-diose]

Yes, I also got some broken ones. Some sellers do bad packaging. And not all syringes are well suited for such use as in the video, because the piston does not move very smoothly. It is necessary to polish it with graphite or with another grinding paste.

[@canaldoectomorfobarrigudo]

Why use the steel wool?

[@grain-diose]

This is necessary to retain warm air at the end of the test tube, so that the piston then moves the warm air.

[@canaldoectomorfobarrigudo]

[@heshamayman7908]

Can i replace the glass syringe by a plastic one ? I think it’s forbidden here so I can’t find a replacement for it , please answer urgently 🙂

1. The plastic syringe burns from the fire and melts from the heat. 2. The plastic syringe has a very tight piston. Moreover, not every glass syringe is suitable. It only suits such that the link - see the description of the video.

Steel wool does not allow heated air to move quickly to the other end of the tube. This function is performed by the piston. Do you think a plastic syringe will withstand fire? Of course, a plastic syringe is not suitable for this engine.

[@yt.user-zull]

Please make another video and explain the working mechanism of the piston in this machine! I guess, the heated (expanded) air will create extra pressure on the walls of the piston chamber and thus it will push the piston outside and it will never pull it back, it will push it continuously outwards. So, me and people can't understand how it pulls the piston back again? Rather than just answering me here, please explain the working mechanism of this thermoacoustic engine in a video...if you explain it, me and most of your subscribers will appreciate you!

[@blg53]

@@yt.user-zull The flywheel carries the expansion momentum over the Top Dead Centre and due to its inertia creates a compression pulse. This pulse travels back into the tube with the speed of sound and pushes the hot air with it to the cold (far) part of the steel wool. The air cools down and thus creates suction force that pulls the piston in. Again the flywheel carries the suction momentum over the Bottom Dead Centre and creates the expansion pulse that bring the air back to the hot part of the tube where it heats up and expands and the cycle repeats. :o)

It will not work. The steam chamber , the piston tube and the piston itself are in the same channel. Hence, the pressure is outward. Given the fact that it has no exhaust meaning the steam gets collected and eventually kick the piston out. But piston is rigid therefore, the chamber itself will explode.

from the wheel and since the volume increased the heat goes down and pressure decreases allowing the piston to go back then heat in the area increases then pressure builds up then pushes the piston out again and again.
