Characterization of Turbulent Flow

Length scale of Turbulence:

  • The distance covered by an eddy before it disappears or loses its identity.

Intensity of Turbulence:

  • Measure of violence of eddies.

Turbulence Intensity:

 

Length Scales used in Turbulent Flow:
  1. Macroscopic scale, L (Characteristic width of flow)
  2. Integral Scale,
  3. Taylor micro scale,
  4. Kolmogorov length Scale,
