Nicole Sharp<p><strong>See the Solar Wind</strong></p><p>After a solar prominence erupts, strong solar winds flow outward from the sun, carrying energetic particles that can disrupt satellites and trigger auroras if they make their way toward us. In this video, an instrument onboard the ESA/NASA’s Solar Orbiter captures the solar wind in the aftermath of such an eruption. The features seen here extended 3 solar radii and lasted for hours. The measurements give astrophysicists their best view yet of this post-eruption relaxation period, and the authors report that their measurements are remarkably similar to results of recent magnetohydrodynamics simulations, suggesting that those simulations are accurately capturing solar physics.

Nicole Sharp<p><strong>Bow Shock Instability</strong></p><p>There are few flows more violent than planetary re-entry. Crossing a shock wave is always violent; it forces a sudden jump in density, temperature, and pressure. But at re-entry speeds this shock wave is so strong the density can jump by a factor of 13 or more, and the temperature increase is high enough that it literally rips air molecules apart into plasma. </p><p>Here, researchers show a numerical simulation of flow around a space capsule moving at Mach 28. The transition through the capsule’s bow shock is so violent that within a few milliseconds, all of the flow behind the shock wave is turbulent. Because turbulence is so good at mixing, this carries hot plasma closer to the capsule’s surface, causing the high temperatures visible in reds and yellows in the image. Also shown — in shades of gray — is the vorticity magnitude of flow around the capsule.

Nicole Sharp<p><strong>Fractal Fingers</strong></p> <p><a class="" href="https://fyfluiddynamics.com/wp-content/uploads/sti1.png" rel="nofollow noopener" target="_blank"></a></p> <p><a class="" href="https://fyfluiddynamics.com/wp-content/uploads/sti2.png" rel="nofollow noopener" target="_blank"></a></p> <p><a class="" href="https://fyfluiddynamics.com/wp-content/uploads/sti3.png" rel="nofollow noopener" target="_blank"></a></p> <p></p> <p>As bizarre as the branching fractal fingers of the Saffman-Taylor instability look, they’re quite a common phenomenon. In his video, Steve Mould demonstrates how to make them by sandwiching a viscous liquid like school glue between two acrylic sheets and then pulling them apart. The more formal lab-version of this is the Hele-Shaw cell, which he also demonstrates. But you may have come across the effect when pealing up a screen protector or in dealing with a cracked phone screen. In all of these cases, a less viscous fluid — specifically air — is forcing its way into a more viscous fluid, something that it cannot manage without the fluid interface fracturing.

Continued thread

For crying out loud, like a drunk toddler & for seemingly no reason at all, #Trump has now reversed his #tariffs on #Canada.
Trump said Thurs that he would allow BOTH #Mexico & Canada to avoid tariffs on most exports to the #US for 1 month, specifically products subject to the #USMCA, the #trade pact he signed in his first term.
The move came less than a day after he granted a 30-day reprieve to #automakers, & hours after announcing a pause on Mexico’s tariffs.

Continued thread

For rank-and-file workers, the latest move by #Musk underscored a climate of #instability & #fear inside the #FederalGovernment. One staff member at the National Institutes of Health, who spoke on the condition of anonymity out of fear of retaliation, said she was shocked by the message, which she said left her with a sick feeling in the pit of her stomach. When she found out more of the context, she said, she messaged a colleague: “They’re terrorizing us.”

Visualizing Unstable Flames

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 parametric resonance, where the flame’s instability is fed by system’s natural harmonics. (Video and image credit: J.
