Wanying Kang on tides, heat transport and baroclinic dynamics in Enceladus and Europa under-ice ocean #astrodon #science #FluidMechanics

Three mathematicians have derived the fundamental PDEs of #FluidMechanics, such as the compressible Euler and incompressible Navier-Stokes-Fourier equations, starting from hard sphere particle systems undergoing elastic collisions. They claim it resolves #Hilbert's sixth problem. By mathematically proving how individual molecules create the complex motion of #fluids, the three mathematicians could have helped to illuminate why time can not flow in reverse.

flying north from Ōtautahi yesterday afternoon and this had all the #FluidMechanics - waves, sunglint on braided rivers, clouds, and best of all lift keeping us in the air. Unfortunately the latter was a little conditional as we had some engineering issues that sent us back to CHC and so my dreams of a nice friday afternoon cuppa at home evolved into two more flights to get home about 1030pm and not in the mood for a cuppa. #FirstWorldProblems

it is kind of wild to learn that #FluidMechanics played an integral role in the creation of #CUDA and in turn ushering in an era of #GPGPU and #AI

In #FluidMechanics, things like #SurfaceWaves are often modelled using #LinearEquations, which give rise to phenomena such as the principle of #LinearSuperposition, where you can take two or more distinct solutions and simply add them together to get a new solution. Solutions are also periodic and can be decomposed into sinusoidal functions.

An Article in the Annual Review of Condensed Matter Physics on Turbulence by KR Sreenivasan and J Schumacher
https://www.annualreviews.org/content/journals/10.1146/annurev-conmatphys-031620-095842

What is the turbulence problem, and when can we say it’s solved? 🌪️ This deep dive by Sreenivasan & Schumacher explores the math, physics, and engineering challenges of turbulence—from Navier-Stokes equations to intermittency and beyond. A must-read for anyone fascinated by chaos, complexity, and the unsolved mysteries of fluid dynamics! 🌀

A summary of the talk presented by KR Sreenivasan in December 2023 at the International Center for Theoretical Sciences (ICTS-TIFR) in Bengaluru, as part of a program on field theory and turbulence.

The annual “VKI PhD Symposium" is currently taking place. There is a new tradition to have some keynotes off the beaten track, and today it was about the risks of #AI. Food for thought!

Edit: one of the speakers is here on Mastodon: @SylviaFysica

Happy birthday, Clifford Truesdell! 🎂 🪐 🌊 🎓

Just took a break from my pooter to heave my corpulent meatsack self to my ensuite to belatedly brush my teeth after brekkie. Stooped over my handbasin, doing the doings, i realised that parts of my face were being randomly splashed, so i returned my mind from zooming along the astral plane to consider what might be happening.

Realised that i'd forgotten to turn the cold tap fully off as i began brushing, that the combo of its consequent partial valve opening, the cooler than usual day, & the local water pressure today had combined to make the resultant waterflow's #ReynoldsNumber fully turbulent, not laminar. Furthermore, the ensuing randomness of its flow in this mode was such that often it was striking the basin drain grate grills rather than falling cleanly thru the gaps, & was rebounding aka splashing. Finally, my stoop was sufficient that my face happened to be in just the right range to intersect with this mild local splashing.

These contemplative revelations pleased me. It was a nice little low-key local demonstration that no matter the pomposity, arrogance, & suicidal determination of the ridiculous human species, the principles of #physics, #thermodynamics, #fluidmechanics, & #chaostheory will always prevail.

But i expect such thoughts regularly cross the minds of most peeps as they do their routine ablutions... 🤷‍♀️ 🤭 😜

Snuck off to the #DoctorWho exhibition in town before it closes. It was fun, quite sciency actually. Even a little #FluidMechanics 🌀.And some great bits n bobs from the show… also my first time inside #Tākina. I’m warming to it.

Dear fellow physics teachers (especially of continuum-mechanics-related disciplines): do you have any suggestions, thoughts, personal experiences, and references about nice *graphical representations* of the flux of a vector quantity – for instance momentum flux (in momentum transport)?

Cheers!

PS: what tags can be good & appropriate for a request like the present one?

I'm #hiring ! Jose Montoya and I are looking for a PhD student to join our new CNRS-funded project on theoretical & numerical modelling of the spatial and scale-dependency of biodiversity and ecosystems.

Details of project and job description in links below (project is hosted at SETE in Moulis #Ariège, France)

It's a truly interdisciplinary project, so pinging the #ecology #ecoevo #physics #FluidMechanics teams here 🙂

Even though the Navier–Stokes equations are deterministic, it seems that you cannot make predictions beyond a fixed time horizon, no matter how small the initial uncertainty. #physics #fluidmechanics

Fascinating:

"Unraveling the ultrafast polar tube ejection in microsporidia reveals extreme cellular hydraulics, providing a data-driven model for infectious cargo transport, with implications for physical approaches to understanding microsporidia transmission."

Much like the world of Hogwarts snd the duality of magic and dark arts, #FluidMechanics also has a dark side.

Good applications ranges from microscale (biofluids, medicine, elerctronics) to earth and space, (where understanding heat, wind, water helps weather forecasting, renewable energy, and transporting sectors)

On the flip side there:

1. shock waves and hypersonic flows, which can be structured as pure studies, but has profound applications in military.
2. fracking: oil and gas!
