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>

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.

Peter Schaar (en)For the guardian angel of the <a href="https://eupolicy.social/tags/combustion" class="mention hashtag" rel="tag">#combustion</a> engine, German Transport Minister Volker <a href="https://eupolicy.social/tags/Wissing" class="mention hashtag" rel="tag">#Wissing</a>, the compromise proposal of the <a href="https://eupolicy.social/tags/EU" class="mention hashtag" rel="tag">#EU</a> <a href="https://eupolicy.social/tags/Commission" class="mention hashtag" rel="tag">#Commission</a> does not go far enough. The proposal corresponds exactly to the demands of the <a href="https://eupolicy.social/tags/FDP" class="mention hashtag" rel="tag">#FDP</a> to continue to bring such vehicles into circulation after 2035, which can drive exclusively with <a href="https://eupolicy.social/tags/eFuel" class="mention hashtag" rel="tag">#eFuel</a>.
