Inertial subrange

Web11 apr. 2024 · An inertial subrange with a −5/3 power law between 0.9 and 5 Hz which is in a narrow range was observed. There is transitional subrange between 0.6 and 0.9 Hz which corresponds to transition between the production subrange and the inertial subrange.

An Inertial Subrange in Microstructure Spectra

Web20 feb. 2012 · inertial subrange An intermediate range of turbulent scales or wavelengths that is smaller than the energy-containing eddies but larger than viscous eddies. In the inertial subrange, the net energy coming from the energy-containing eddies is in equilibrium with the net energy cascading to smaller eddies where it is dissipated. WebThe existence of the inertial subrange for the (incompressible) Navier-Stokes equations has been proven. In this paper, we proof the same result for any skew-symmetric regularization of the nonlinearity in the Navier-Stokes equations. A simple dimensional analysis gives then Kolmogorov’s -5/3 spectrum.

Web11.6.2 Inertial Subrange Equation (11.104) is valid only if the refractive index scales, of size Λ equal to half the radar wavelength, lie within the inertial subrange of turbulence scales. In this range the rate at which turbulent energy is transferred to smaller scales as large eddies fragment depends only on the dissipation rate ε of turbulent energy.
