NFDI4ChemThe next Stammtisch is coming up!On 25 April, Dr Kai Moshammer-Ruwe will talk about ‘Unlocking insights – how a data base can drive progress in combustion <a href="https://nfdi.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> ’<a href="https://nfdi.social/tags/Combustion" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Combustion</a> is still important. It's good to know that scientists are still looking into it. And as with many other sciences, a lot of the focus these days is on data.<a href="https://bit.ly/4hmr3k0" rel="nofollow noopener noreferrer" target="_blank">https://bit.ly/4hmr3k0</a> <a href="https://nfdi.social/tags/laboratory" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#laboratory</a> <a href="https://nfdi.social/tags/standard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#standard</a> <a href="https://nfdi.social/tags/fair" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fair</a> <a href="https://nfdi.social/tags/data" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#data</a> <a href="https://nfdi.social/tags/chemie" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chemie</a> <a href="https://nfdi.social/tags/chemistry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chemistry</a>

ClocksImagine how unstable a fusion combustion engine would be?The premise would be that you'd have 3 pistons, each feeding a crank shaft connected to a generator.You'd also have this underwater or some other coolant as to siphon the heat away, maybe add a turbine to the shaft to help move the liquid away from the pistons.The first combustion either blows up everything, rips the shaft apart, or provides just enough force to force the next piston to combust. <a href="https://lemmy.ml/comment/17256293" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://lemmy.ml/comment/17256293</a><a href="https://cyberpunk.lol/tags/Fusion" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Fusion</a> <a href="https://cyberpunk.lol/tags/Engineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Engineering</a> <a href="https://cyberpunk.lol/tags/Engine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Engine</a> <a href="https://cyberpunk.lol/tags/Combustion" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Combustion</a>

Nicole SharpVisualizing Unstable Flames <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/thermo_instab1.gif" rel="nofollow noopener noreferrer" target="_blank"></a> <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/thermo_instab2.gif" rel="nofollow noopener noreferrer" target="_blank"></a> <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/thermo_instab3.png" rel="nofollow noopener noreferrer" target="_blank"></a> Inside a combustion chamber, temperature fluctuations can cause sound waves that also disrupt the flow, in turn. This is called a thermoacoustic instability. In this video, researchers explore this process by watching how flames move down a tube. The flame fronts begin in an even curve that flattens out and then develops waves like those on a vibrating pool. Those waves grow bigger and bigger until the flame goes completely turbulent. Visually, it’s mesmerizing. Mathematically, it’s a lovely example of <a href="https://en.wikipedia.org/wiki/Parametric_oscillator" rel="nofollow noopener noreferrer" target="_blank">parametric resonance</a>, where the flame’s instability is fed by system’s natural harmonics.

millerebonds5 Fabrication de la paroi intérieure de 43mm de haut. Elle se cale parfaitement avec le cul de canette, avec son sillon circulaire. J'agrafe pour maintenir fermé et au bon diamètre cette paroi. Agrafer parfaitement contre une deuxième bande de 43 c'est bien, plus solide, et permet de bien maintenir la pression (je crois). Ne pas oublier les deux entailles du bas, qui permettent à l'alcool de passer de l'autre côté ! <a href="https://framapiaf.org/tags/combustion" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#combustion</a> <a href="https://framapiaf.org/tags/surcyclage" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#surcyclage</a> <a href="https://framapiaf.org/tags/suprarecyclage" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#suprarecyclage</a>
