Scaling properties in the production range of shear dominated flows
C. M. Casciola, P. Gualtieri, B. Jacob +1
Recent developments in turbulence are focused on the effect of large scale anisotropy on the small scale statistics of velocity increments. According to Kolmogorov, isotropy is rec…
Drag Reduction by Polymers in Turbulent Channel Flows: Energy Redistribution Between Invariant Empirical Modes
Elisabetta De Angelis, Carlo M. Casciola, Victor S. L'vov +2
We address the phenomenon of drag reduction by dilute polymeric additive to turbulent flows, using Direct Numerical Simulations (DNS) of the FENE-P model of viscoelastic flows. It…
Homogeneous isotropic turbulence in dilute polymers: scale by scale budget
E. De Angelis, C. M. Casciola, R. Benzi +1
The turbulent energy cascade in dilute polymers solution is addressed here by considering a direct numerical simulation of homogeneous isotropic turbulence of a FENE-P fluid in a t…
Scale by scale budget and similarity laws for shear turbulence
C. M. Casciola, P. Gualtieri, R. Benzi +1
Turbulent shear flows, such as those occurring in the wall region of turbulent boundary layers, manifest a substantial increase of intermittency with respect to isotropic condition…
Double scaling and intermittency in shear dominated flows
C. M. Casciola, R. Benzi, P. Gualtieri +2
The Refined Kolmogorov Similarity Hypothesis is a valuable tool for the description of intermittency in isotropic conditions. For flows in presence of a substantial mean shear, the…
Scaling laws and intermittency in homogeneous shear flow
P. Gualtieri, C. M Casciola, R. Benzi +2
In this paper we discuss the dynamical features of intermittent fluctuations in homogeneous shear flow turbulence. In this flow the energy cascade is strongly modified by the produ…
