The kinematics and dynamics of wall-bounded turbulence are surveyed, with emphasis on
the multiscale processes associated with the logarithmic layer and with its interactions with …

Fluid dynamics turbulence refers to the chaotic and unpredictable dynamics of flows.
Despite the fact that the equations governing the motion of fluids are known since more than …

The problem of anisotropy and its effects on the statistical theory of high Reynolds number
(Re) turbulence (and turbulent transport) is intimately related and intermingled with the …

A shear-improved Smagorinsky model is introduced based on results concerning mean-
shear effects in wall-bounded turbulence. The Smagorinsky eddy-viscosity is modified as …

Real turbulent flows are difficult to classify as either spatially homogeneous or isotropic.
Nonetheless these idealizations allow the identification of certain universal features …

The statistical properties of wall turbulence in the logarithmic region are investigated using
structure functions of the streamwise velocity. To this end, datasets that span several orders …

The effects of different filtering strategies on the statistical properties of the resolved-to-
subfilter scale (SFS) energy transfer are analysed in forced homogeneous and isotropic …

A method to simulate the effects of a roughened surface on a turbulent boundary layer is
introduced. The method is easy to implement, does not increase the numerical overhead of …

The turbulent flow originating from the interaction between two parallel streams with different
velocities is studied by means of direct numerical simulation. Rather than the more common …

Turbulent shear flows, such as those occurring in the wall region of turbulent boundary
layers, show a substantial increase of intermittency in comparison with isotropic conditions …
