Exact regularized point particle method for multi-phase flows in the two-way coupling regime
P. Gualtieri, F. Picano, G. Sardina +1
Particulate flows have been largely studied under the simplifying assumptions of one-way coupling regime where the disperse phase do not react-back on the carrier fluid. In the con…
Anisotropic clustering of inertial particles in homogeneous shear flow
P. Gualtieri, F. Picano, C. M. Casciola
Recently, clustering of inertial particles in turbulence has been thoroughly analyzed for statistically homogeneous isotropic flows. Phenomenologically, spatial homogeneity of part…
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…
Anisotropic fluctuations in turbulent sheared flows
Boris Jacob, Luca Biferale, Gaetano Iugo +1
An experimental analysis of small-scales anisotropic turbulent fluctuations has been performed in two different flows. We analyzed anisotropic properties of an homogeneous shear fl…
Drag Reduction by a Linear Viscosity Profile
Elisabetta De Angelis, Carlo Casciola, Victor S. L'vov +3
Drag reduction by polymers in turbulent flows raises an apparent contradiction: the stretching of the polymers must increase the viscosity, so why is the drag reduced? A recent the…
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…
