Condition for noise to occur along with an example for a diffusion equation
H. Mouri
While noise is ubiquitous and has been found in various systems, its physics remains uncertain. From an analytical study of an ordinary diffusion equation, we find an additio…
Momentum flux fluctuations in wall turbulence formulated along the distance from the wall
H. Mouri, J. Ito
Wall turbulence has a sublayer where the mean wall-normal flux of the streamwise momentum is constant. Via the law of the wall, this mean flux is related to the wall-normal profile…
Momentum flux fluctuations in wall turbulence: a formula beyond the law of the wall
H. Mouri, J. Ito
Within wall turbulence, there is a sublayer where the mean wall-normal flux of the streamwise momentum is constant and related to the logarithmic wall-normal profile of the mean st…
Logarithmic and nonlogarithmic scaling laws of two-point statistics in wall turbulence
H. Mouri, T. Morinaga, T. Yagi +1
Wall turbulence has a sublayer where one-point statistics, e.g., the mean velocity and the variances of some velocity fluctuations, vary logarithmically with the distance from the…
Unlikely existence of spectral law in wall turbulence: an observation of the atmospheric surface layer
H. Mouri, T. Morinaga, S. Haginoya
For wall turbulence, there has been predicted a range of streamwise wavenumbers such that the spectral density of streamwise velocity fluctuations is proportional to $k_x^{-1…
Logarithmic scaling for fluctuations of a scalar concentration in wall turbulence
H. Mouri, T. Morinaga, T. Yagi +1
Within wall turbulence, there is a sublayer where the mean velocity and the variance of velocity fluctuations vary logarithmically with the height from the wall. This logarithmic s…
