Turbulence is indeed an unsolved problem both in physics and mathematics. Whether it is the "greatest" might be argued but for lack of good metrics probably for a long time. Why it is an unsolved problem …

Sep 26, 2022 · a newbie in turbulence study, very confused about the concept of eddy, I feel the word "eddy" having two meanings in fluid-mechanics maybe more and i'm not sure if i …

Jan 5, 2021 · IV lines must be regularly ‘flushed’ to avoid infection and line occlusion. More turbulent flushing better removes any particles attached to a catheter wall, which decreases chances of …

Apr 11, 2021 · Just an observation from lots of air travel experience. I have found that, typically, when approaching a landing turbulence diminishes the closer you get to the ground.

Jul 13, 2020 · For example, if i have a horizontal orifice plate in a tube and i'm pushing flow through it, there will be significant turbulent mixing downstream of the orifice plate. E.g. https://www.youtube.com...

Feb 7, 2015 · As far as I understand, in general, turbulence describes the process of transfer of energy from a large scale, at which a system is perturbed, to a small scale, where dissipation happens. At …

Sep 17, 2024 · I can imagine that a stronger gravitational pull would cause water molecules to push harder against the lower pipe wall and less hard on the upper pipe wall. But how would turbulence be …

May 13, 2016 · In high Reynolds numbers we have turbulent flow. This is because the inertial forces are much greater than the viscous forces. I understand inertial forces to be actually the fictional forces …

Jun 3, 2024 · Someone described to me the difficulty of numerically simulating turbulence as that as you look at smaller length scales you see more structure like you do in a fractal. Searching on google for 'f...

Aug 30, 2022 · The Euler equation models perfectly inviscid fluids. Under this assumption, with $\\nu = 0$, the Reynolds number should be infinite. I would guess that this implies the Euler equation is …
