Oct 3, 2020 · This term is turbulence kinetic energy dissipation rate $\epsilon$, which represents the rate at which Kolmogorov eddies energy is converted back into the flow’s internal energy. I …

Dec 26, 2022 · In this Wikipedia article, Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason …

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 …

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 …

How do I determine if the vortex so formed is laminar or turbulent? The flow in your case will have some 'lamina' features and be fully turbulent. To establish the dominating factor in this case …

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 …

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 …

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?

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 …
