Блин!!!!!!!!!!!!!! Мистика какая -то!!!!!)))) Несколько дней уже обдумываю - не сделать ли паровой двигатель , и для опять же будущего генератора (мысли магнитные кружатся )))!!!) и даже для чего нибудь, что по по снегу двигаться будет и этот чёртов снег убирать! Само собой даже картинка подобная, на белом , "заснеженном" поле перед глазами мерещилась!!! (Мысленные эксперементы!!!) И вот тебе - на!!!))) Как говорится сон - в руку , а тут фантастика, такое совпадение - Видео - руку!)))) Не вру в натуре, немного даже в шоке!!!)) Прям какой - то знак свыше!!!))) Классный видос!!! Лайк!
Cool 😎 project…. Wonder if you can use a long single glass syringe to power the thermostatic engine instead of an additional test tube at the end?? Thx
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
Great job! Thank you for sharing it. Just an observation: in the materials section (0:43) you wrote "glass siringe 20 mL", but the syringe you use is a 10mL one.
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.
um salve do Brasil + like. máquinas como essas são incríveis. até a NASA se interessou por elas na corrida espacial usando espelhos para concentrar a radiação solar. tá uma ideia pra um vídeo: Motor Stirling solar. parabéns.
Yes, I also did not perfect, in this engine, it is important to thorough mechanical accuracy and rigidity. This applies especially to the flywheel, it should be done on a lathe, but my flywheel is made by hand.
did it work? cause were making project to light up an led and we saw a video in youtube that mislead us and now were going to start all over again thank you
Una pregunta,ese motor funcionaria con el calor del sol enfocado a traves de una lupa??...y si tiene cierto torque..para poder colocar una pequeña dinamo
I don’t know, try it, but if it is thicker, it may work worse. What I used can be bought, I give links under the video to the materials that you can buy. www.aliexpress.com/item/32702827031.html
@grain, can u tell me specifically what materials did you use in the thermoacoustic engine, including the wood, those rubber things in the screws, and the measurements too of the wood and that peg that fastens the wheel? Thanks.
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.
Links to materials are in the video description. Steel wool is needed so that the heated air does not move independently, it is moved by the piston. www.aliexpress.com/item/32702827031.html
I did not understand how this single-cylinder engine works when the heat causes the air inside the cylinder to expand, so how does the piston go backwards?
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.
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! Do it please!
I do not speak English. And I myself do not understand the principle of thermoacoustics. Have wikipedia - en.wikipedia.org/wiki/Thermoacoustic_heat_engine
@@zulfequar_ali 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)
Do you know if it works, if i use a test tube of 16x150ml?, because i can't find a test tube of 15x150ml nearly or it's necesary change the syringes too?
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 - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gYfrKMgy_Pg.html
I can not correctly explain, but in the Stirling engine there are two cameras. And if I’m not mistaken, there is a resonant frequency, but not in Stirling.
At the beginning of the 0:37 video, I wrote about the materials. A syringe of 10 ml (wrongly wrote 20 ml), a test tube 15x150 mm. Links are under the video.
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.
Просто умница! Ай да молодец! Осталось довести до инженерного решения, до реального механизма. Пока как забава - прикольно. Надо найти сучар абрамовичей, прохоровых, грефов...
This video is awesome and very good........But i want another video which is very simple to do by using only 3 to 4 materials which we can buy easily in electronic shop and it will easy to make... in some week in my school their is sci exhibition and i use only your ideas so plz plz plz make some thing easy for me plz plz plz 😢😢😢😢👍👍
