Apr 1, 2020 · I think the dimensional analysis @2b-t linked to is the way it is derived. The K41 paper outlines the hypotheses of turbulence, and then dimensional analysis is what determines the …

What is called turbulence are precisely those states where the flow is irregular. However as this transition to turbulence depends on the constituents and parameters of the system and leads to very …

Apr 11, 2021 · The turbulence seems to increase with height from the surface. Then let's look at wind flowing over ground. The picture below is from this website. Now here there is an obstruction on the …

Jan 21, 2025 · Wikipedia [1] says after the constriction in the pipe, that we don't see the pressure return to p1 due to turbulence. Am I right to believe that further downstream if the pipe has returned to its …

Sep 21, 2024 · I have been trying to work through R. H. Kraichnan's seminal 1967 paper on two-dimensional turbulence [Inertial Ranges in Two-Dimensional Turbulence, Phys. Fluids 10, …

Dec 22, 2024 · Turbulence is not predictable in the sense that from one instant in time to the next a region of water will behave unpredictable. A von Karman vortex - flagpole vortex - for example is …

Aug 30, 2022 · Turbulence is the time-dependent chaotic behaviour seen in many fluid flows. It is generally believed that it is due to the inertia of the fluid as a whole: the culmination of time …

Oct 1, 2013 · I haven't been able to understand what are does someone mean by length and time scales, while talking about turbulence. Can someone explain it?

The explanation of shear rate in laminar flow is straightforward: We imagine small layers of fluid that glide on each other. Now, in turbulent flow, this does not work as there are no layers. I'm not

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 …
