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 …

Aug 4, 2011 · According to Kolmogorov, the energy spectrum function of a turbulent fluid is given as, $E (k)=C\epsilon^ {\frac {2} {3}}k^ {\frac {-5} {3}}$ where $\epsilon$ is the ...

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 …

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 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 …

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 …

Feb 7, 2015 · This is called turbulence. In the context of turbulence, one often comes across the term "weak" and "strong" turbulence. Both lead to energy cascades, but the difference between the two …
