How can we make the Fediverse more positive and wholesome? in c/asklemmy@lemmy.world

Generously start using CWs (Content warnings) as folks used to do in the early days of Fediverse.

It is not the default because it can also break meaningful functionality.

Sounds like a perfectly normal take.

There, FTFY.

What is the turbulence problem, and when can we say it’s solved? in c/physics@mander.xyz
[–] jadelord@discuss.tchncs.de 2 points 6 months ago

I agree. Also, if you gave tons of compute power and DNS using Navier Stokes, it may feel that with CFD provides an answer; although it is approximate, it is a decent one. To me, the issue is every single time we do practical CFD of a whole city or an automobile etc. , we need specialized models that fit the flow regime. Even with petascale compute power that most supercomputers in the world are equipped with, once we simulate Navier Stokes + a turbulence model + some custom boundary condition + other microscale model, the approach is not generalizable and needs deep knowledge.

Rheology of rubbing mud reveals that it is "shear thinning". It rubs like lotion and fills in the holes.

Great if it is done right. This will put a stop all those screenshoted memes from Fediverse.

Is there no electromagnetic force between the positively charged nucleus of an atom and the electrons? (discuss.tchncs.de)

Or in other words which forces keep electrons in orbitals and prevent it from flying away or crashing into the nucleus according to modern understanding?

TLDR: To remove by shaking one would need accelerations high as 24g, which can damage the ear. A couple drops of vinegar or alcohol in the ear will lower the surface tension and make the fluid easier to remove

AMA! Ph.D. in geophysical fluid mechanics and stratified flows (discuss.tchncs.de)
 

cross-posted from: https://discuss.tchncs.de/post/479621

Hi all! I defended my Ph.D. thesis back in 2019 and I also served as the creator and moderator for the subreddit r/FluidMechanics for a long time. I think with that I have gathered enough experience and courage to answer some of your queries. Some broad topics that I can answer questions on are:

  • computation fluid mechanics
  • scientific programming and HPC
  • nonlinear shallow water equations
  • statistical description of turbulence: spectra, energy budget etc.
  • experimental methods: PIV
  • stratified turbulence
  • academia
  • navigating your career pre- and post-Ph.D.

Ask away!
