Supersonic (Mach 3) flow around cylinder

Supersonic flow around cylinder (Mach 3)

The simulation was done with 2.4 million degrees of freedom (continuous Q1 finite elements) per component.

This is the definition of beauty! Absolutely mesmerizing

[FourOf]

so what you're saying is I probably shouldn't swim in it

[KW-]

I think you need to have a bigger domain. There is a strong wall influence in the simulation & looks weird.

[canerkoyuncu]

damn this lines has got meaning and beauty at the same time

[takahashun]

I'd really like to see the experimental results under the same conditions as this numerical analysis. Anyone want to try the experiment?

[rtensor]

Wow, at first I thought this was a film of an experiment.

[little_star-nz]

good job. I wonder whether this program can be extended to compressible multi-phase flow?

[Nightrunnergunner]

🥱 looks like that old screensaver from those early 2000s computers. 50hrs. wohoo..

[hoffmannnatan]

Awesome video. Can you share the initial and boundary conditions you used?

[traveloguebySandeep]

Why that oscillating shocks are not interacting with the KH instabilities?

[Alexander_Sannikov]

how come the first shock is not reflected off the top/bottom boundaries, but consequent shocks are? besides, those strange standing waves along the first shock front -- are they numerical artefacts or are they a physical thing?

[MA-nxxj]

Amazing!!
Is the extremely high resolution a consequence of using fine grids or something else?

[PedroGarcia-ibtt]

Nice video. Can you provide the color map that you used in it ?

[betabenja]

why don't. the cortices distort when they go through the shockwaves? it's like they maintain all their pressure/velocity information despite travelling through a wall of comparatively infinite pressure gradient

[kalakala]

Is it a pillar in very very high wind or a round bullet going super super fast ? Isn't relativity fascinating ?

[moranezra]

Very nice visualization!
It looks like the initial velocity field is not zero. It means (if I'm correct) that the initial shock diffraction is not realistic.
Can you specify if it is viscose fluid and if so, what is the Re number?

[JohnSmith-ofgu]

This is cool! Do those thick lines represent boundaries between some sort of regions, or are they physical shock waves or something?

[davidvce]

how to install and run this software? i ask because the link tutorial proportioned by main source in github is down

[jianfang]

Hi, nice result. Congrates. What scheme did you use for the simulation?

[BhanudaySharma]

Why are shock waves reflecting from top and bottom boundaries?
