What is the difference between vortexing and centrifuging?
Feb 4, 2016 · I understand that vortexing will result in mixing / re-suspension of particles, and that centrifugation will result in the separation of particles. However, what is the difference in the physics …
Prevention of fluid vortex formation - Physics Stack Exchange
Jun 15, 2016 · Maybe use multiple holes, so that the spin of one vortex will counter the spin of the others.. assuming they all rotate in the same direction (which might be likely, because the origin of …
Vortex in a pipe / Solutions or approximations?
Feb 11, 2016 · The objective is to design a structure that would intentionally cause a vortex to form in a pipe. The goal is to cause a fluid to pass by a series of illuminators and enable uniform illumination …
(How) Does A Vortex Speed Drainage? - Physics Stack Exchange
May 7, 2013 · When a sink drains it forms a vortex. Does that vortex speeds drainage. If yes, how does the vortex speed drainage? The only relevant thing I could find was an expensive article and a …
special relativity - Why does the correlation between recessional ...
Sep 27, 2024 · Why does the correlation between recessional velocity derived from redshift diverge from the velocity obtained via Hubble's Law at high redshifts?
How do you calculate the recession velocity? - Physics Stack Exchange
May 26, 2018 · $\Delta \lambda$ will not be the same for all changes.
Why does a vortex last so long? - Physics Stack Exchange
Sep 6, 2019 · As an interesting aside, when doing modeling of fluid flows, some methods leverage the fact that vortexes are so long lasting and predictable. They detect them, "pull them out" of the …
How do you calculate vortex shedding frequency?
So how this is done is a bit of a black art, much like how you choose what to use for other non-dimensional numbers in fluids (like Reynolds number). But you sort of have it backwards. You don't …

May 15, 2018 · Equation 1 (page 5) in “Expanding Confusion: common misconceptions of cosmological horizons and the superluminal expansion of the universe” by Davis and Lineweaver gives the general …
What are the principles behind foam formation?
As I had a MSc thesis that had to regard this problem within it, did look into this extensivelly. For Beer formation it would be good for you to read , tho it's an older PhD thesis, it was checked and backed …
