Spectral characteristics of surface-layer turbulence

WebLocal equilibrium is found in the inertial subrange and in (at least in part of) the intermediate range, characterized by different slopes upwind and downwind (k−1 and k−5/3, respectively) for the components parallel to the terrain. Similar Items. Web1 dec. 2024 · The inertial subrange had not been identified in vertical temperature microstructure spectra until a recent paper in which one case in the surface layer was described [Gregg and Sanford, 1980]. Batchelor [1959] suggests that the Batchelor form may be found even if the Reynolds number is not high enough for an inertial range to exist. WebThe relation between wind, momentum flux, roughness and land-use in disturbed, non-homogeneous boundary layers is studied. Key questions are: ``how is the roughness related to land-use?'', ``how are wind and friction related to the upstream land-use and roughness?'', and ``is Monin-Obukhov theory still useful over non-homogeneous terrain?''.

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.

WebAssuming that the inertial forces are relevant when studying building natural ventilation, a non-dimensional relationship CvCt/Cl ¼ 1 (or Cv/(ClCf) ¼ 1) may be applied. The model results are therefore valid for the prototype conditions where CvCt ¼ Cv/Cf ¼ 250.
