Universal mean velocity profile in polymeric flows at maximum drag reduction
Francesco Serafini, Francesco Battista, Paolo Gualtieri +1
Provided a sufficient concentration of long-chain polymers in a Newtonian solvent, turbulent wall-bounded flows exhibit a universal state known as Maximum Drag Reduction (MDR). Thr…
Assessment of the point-wise approach for the Turbulent Settling of finite-size particles
Francesco Battistaa, Sergio Chibbarob, Paolo Gualtieria
We study the settling of suspensions of relatively large particles with a diameter of the order of ten Kolmogorov scales and density slightly larger than the carrier fluid in stati…
Exact regularized point particle (ERPP) method for particle-laden wall-bounded flows in the two-way coupling regime
Francesco Battista, Jean-Paul Mollicone, Paolo Gualtieri +2
The Exact Regularized Point Particle (ERPP) method is extended to treat the interphase momentum coupling between particles and fluid in the presence of walls by accounting for the…
Hydrodynamics of flagellated microswimmers near free-slip interfaces
Daniela Pimponi, Mauro Chinappi, Paolo Gualtieri +1
The hydrodynamics of a flagellated microorganism is investigated when swimming close to a planar free-slip surface by means of numerical solu- tions of the Stokes equations obtaine…
Turbulence modulation in heavy-loaded suspensions of tiny particles
P. Gualtieri, F. Battista, C. M. Casciola
The features of turbulence modulation produced by a heavy loaded suspension of small solid particles or liquid droplets are discussed by using a physically-based regularisation of…
Effect of geometry and Reynolds number on the turbulent separated flow behind a bulge in a channel
Jean-Paul Mollicone, Francesco Battista, Paolo Gualtieri +1
Turbulent flow separation induced by a protuberance on one of the walls of an otherwise planar channel is investigated using Direct Numerical Simulations. Different bulge geometrie…
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…
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…
