Mean velocity and length-scales in the overlap region of wall-bounded turbulent flows

  title={Mean velocity and length-scales in the overlap region of wall-bounded turbulent flows},
  author={Y Mizuno and Javier Sampedro Jimenez},
The length scales of the spectra and correlation functions of the velocity fluctuations in the overlap region of turbulent wall-bounded flows are analyzed. It is found that a mixing length based on the mean local shear works better as a normalization than the distance to the wall. To define an overlap range sufficiently long and independent of the Reynolds number to allow the two scalings to be tested, the classical asymptotic expansion of the mean shear is extended to include a near-wall… CONTINUE READING
