Emergence of skewed non-Gaussian distributions of velocity increments in isotropic turbulence
W. Sosa-Correa, R. M. Pereira, A. M. S. Macêdo +3
Skewness and non-Gaussian behavior are essential features of the distribution of short-scale velocity increments in isotropic turbulent flows. Yet, although the skewness has been g…

The Onset of Intermittency in Stochastic Burgers Hydrodynamics
G. B. Apolinário, L. Moriconi, R. M. Pereira
We study the onset of intermittency in stochastic Burgers hydrodynamics, as characterized by the statistical behavior of negative velocity gradient fluctuations. The analysis is ba…
