Spectra of anisotropic turbulent fluctuations of velocity and temperature in turbulent wall flows
Abstract
At sufficiently high Reynolds numbers, smallscale velocity and temperature fluctuations in developed turbulent flows along a solid wall are described by the ordinary laws of the theory of locally isotropic turbulence. It is suggested that, in the region of scales that are substantially greater than the distance to the wall, y, but small in comparison with the external flow scale, the shape of the spectra corresponding to anisotropic fluctuations is not explicitly dependent on y. This hypothesis is supported by measurements for three types of turbulent flows.
