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 understand …

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 …

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?

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 turbulence is …

According to Kolmogorov, the energy spectrum function of a turbulent fluid is given as, E(k) = Cϵ2 3k−5 3 E (k) = C ϵ 2 3 k 5 3 where ϵ ϵ is the energy flux and k = 2π r k = 2 π r where r r is the length scale. …

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 …

May 16, 2023 · While, the Wikipedia article on Turbulence states: In general terms, in turbulent flow, unsteady vortices of many sizes appear which interact with each other; consequently, drag due to …

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 …
