Question

Difference between taylor microscale and kolmogorov scale

Answer 1

Taylor microscale. The Taylor microscale, which is sometimes called the turbulence length scale, is a length scale used to characterize a turbulent fluid flow. ... The Taylor microscale is the intermediate length scale at which fluid viscosity significantly affects the dynamics of turbulent eddies in the flow.

Answer 2

Taylor microscale. The Taylor microscale, which is sometimes called the turbulence length scale, is a length scale used to characterize a turbulent fluid flow. ... In such a flow, length scales which are larger than the Taylor microscale are not strongly affected by viscosity.Of the three standard turbulence length scales, the one that characterizes the smallest dissipation-scale eddies.

Kolmogorov scale : As the turbulence kinetic energy cascades from the largest scales down to the smallest scales, the dynamics of the small eddies become independent of the large-scale eddies. At the smallest scales, the rate at which energy is supplied must equal the rate at which it is dissipated by viscosity.
