Question

According to Kolmogorov, the structure of the smallest eddies depends on ___________

(a) rate of dissipation of kinetic energy

(b) rate of dissipation of turbulent energy

(c) rate of convection of kinetic energy

(d) rate of convection of turbulent energy

The question was posed to me by my school principal while I was bunking the class.

My question is based upon Turbulence Modelling topic in section Turbulence Modelling of Computational Fluid Dynamics

Answer 1

Correct choice is (b) rate of dissipation of turbulent energy

The best explanation: Kolmogorov stated that the structure spectral energy of the smallest eddies depends only on the rate of dissipation of turbulent energy. But later studies revealed that only the spectral energy of the smallest eddies depends only on the rate of dissipation of turbulent energy and not their structure.
