What are the length and time scales in turbulence?
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?
how to determine if a vortex is laminar or turbulent
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 should be …
What causes wind gusts? - Physics Stack Exchange
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 …
Is there any method to apply statistical mechanics to turbulence?
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 …
turbulence - Physical Explanation for "Kolmogorov -5/3 spectrum" in ...
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. …
