Principal Component Analysis (PCA) is the gold standard in dimensionality reduction.

But PCA is hard to understand for beginners.

Let me destroy your confusion:

Cessna 210 | #CFD simulation using #OpenFOAM

Time-Accurate Rotating Propeller (TARP)
OpenFOAM + #snappyHexMesh + Sliding meshes + #paraview + #LES 🤯

Stay tuned for this CFD cookie 🍪.
A lot to learn!!!

Extreme events in turbulence are more universal than expected! In their new Letter, Buaria & Pumir combine simulations and experiments across turbulent flows to show that the extreme velocity gradients behave universally—key for theory and modeling

PRFluids Editor's suggestion: Growth of Rayleigh-Taylor fingers in the interface of a laboratory analog of a porous rock! As the instability develops, the injected fluid can mix more into the formation, which is key for geothermal systems. By Clarke et al. https://t.co/1K3446PS22

I'll finish my Mathematics of Machine Learning book in 2024. Once done, the price goes up from $65 to $100.

You can get it for $49 at the link below. For each purchase, I give out a free copy for someone who can't afford it. (Apply in DM.)

Had a discussion on Roe's fluctuation-splitting scheme, which in 1D is equivalent to the first-order upwind FV scheme. See below if you're interested to know what Roe's fluctuation-splitting scheme is (which drives him to discover the so-called Roe averaging.)

Our Neko paper, headed by @n_jansson from @KTHuniversity is finally out: https://t.co/WgTTs6Zhj6. Have a look at the code at https://t.co/bcxCpjQMyZ!

Fresh from the press, our latest study in @JFluidMech describes how vortex pairs merge in dusty flows. We find an interesting behavior where the dust particles oppose the merger and may even push the vortices a part! More details in: https://t.co/vL1V7OWOcN

Before requesting their removal, I recovered my backups from an old external drive (and revived an ancient Mac Pro with Firewire to get them out!)—I re-uploaded these popular #CFD lectures to my own YouTube channel, and added them to the existing playlist
