Nicole SharpWhy Icy Giants Have Strange Magnetic FieldsWhen Voyager 2 visited Uranus and Neptune, scientists were puzzled by the icy giants’ disorderly magnetic fields. Contrary to expectations, neither planet had a well-defined north and south magnetic pole, indicating that the planets’ thick, icy interiors must not convect the way Earth’s mantle does. Years later, other researchers suggested that the icy giants’ magnetic fields could come from a single thin, convecting layer in the planet, but how that would look remained unclear. Now a scientist thinks he has an answer. When simulating a mixture of water, methane, and ammonia under icy giant temperature and pressure conditions, he saw the chemicals split themselves into two layers — a water-hydrogen mix capable of convection and a hydrocarbon-rich, stagnant lower layer. Such phase separation, he argues, matches both the icy giants’ gravitational fields and their odd magnetic fields. To test whether the model holds up, we’ll need another spacecraft — one equipped with a Doppler imager — to visit Uranus and/or Neptune to measure the predicted layers firsthand.

Nicole SharpHow Cooling Towers Work <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/ct1.png" rel="nofollow noopener noreferrer" target="_blank"></a> <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/ct2.png" rel="nofollow noopener noreferrer" target="_blank"></a> <a class="" href="https://fyfluiddynamics.com/wp-content/uploads/ct3.png" rel="nofollow noopener noreferrer" target="_blank"></a> Power plants (and other industrial settings) often need to cool water to control plant temperatures. This usually requires cooling towers like the iconic curved towers seen at nuclear power plants. Towers like these use little to no moving parts — instead relying cleverly on heat transfer, buoyancy, and thermodynamics — to move and cool massive amounts of water. Grady breaks them down in terms of operation, structural engineering, and fluid/thermal dynamics in this Practical Engineering video. Grady’s videos are always great, but I especially love how this one tackles a highly visible piece of infrastructure from multiple engineering perspectives.

TomKrajci 🇺🇦 🏳️‍🌈 🏳️‍⚧️Time lapse of convective activity along a convergence line on 14 July. Infrared view, which makes the blue sky very dark and the conifers very bright.If you're a glider pilot, this video shows that you want to be at the extreme upwind edge of the cloud formation, just under cloud base. That's the area of best lift.Exposure interval was two seconds. This video represents about 35 minutes of elapsed time.<a href="https://www.youtube.com/watch?v=jqKW30c1sT4" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.youtube.com/watch?v=jqKW30c1sT4</a><a href="https://universeodon.com/tags/NMwx" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NMwx</a> <a href="https://universeodon.com/tags/Glider" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Glider</a> <a href="https://universeodon.com/tags/Convection" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Convection</a> <a href="https://universeodon.com/tags/Convergence" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Convergence</a> <a href="https://universeodon.com/tags/Lift" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lift</a> <a href="https://universeodon.com/tags/TimeLapse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TimeLapse</a> <a href="https://universeodon.com/tags/Infrared" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Infrared</a> <a href="https://universeodon.com/tags/Photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Photography</a> <a href="https://universeodon.com/tags/Soaring" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Soaring</a> <a href="https://universeodon.com/tags/NewMexico" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NewMexico</a>
