  • What is the mystery of turbulence? - Physics Stack Exchange
    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 different states, there exists sofar no general physical theory of turbulence
  • turbulence - From Kolmogorov (1941) to $k^ {-5 3}$ - Physics Stack Exchange
    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 exponent That's consistent with how the K41 paper determines all the other relationships they lay out -- it's all based on dimensional analysis definitions Not sure you'll find "better" demonstrations than
  • Taylors hypothesis in turbulence - Physics Stack Exchange
    The "Taylor Hypothesis" is founded on the idea that the changes observed in any given measured in the propagate at speeds much much less than the bulk flow speed of the solar wind (well, this has been applied in other regions of space than just the solar wind, but it's most commonly assumed there) We start with the nonrelativistic relation (i e , assume V c 1) given by: where is the observed
  • Turbulence after pipe constriction - Physics Stack Exchange
    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 original diameter d1, that both the pressure will match p1 and the velocity will match v1?
  • What are the length and time scales in turbulence?
    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?
  • fluid dynamics - Does wind turbulence increase or decrease with height . . .
    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 flow path This creates turbulence, which is now higher near the ground, and decreases with height
  • Is there any method to apply statistical mechanics to turbulence?
    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 reoetitive, predictable and not turbulent Turbulence is statistical in the sense that over a short period of time there could be a certain probability of a vortex with a given size and energy in a region but
  • What does “eddy” mean in turbulence? - Physics Stack Exchange

    2 I have seen derivations of the the length scale, time scale and characteristic velocity of eddies in the inertial or large-scale range and in the diffusive or Kolmogorov scale range I'm interested in the region in between, which Alistair Revell in his video titled “Advanced CFD Course: Turbulence Scaling” calls the Transfer Scale
