Rotating turbulence under "precession-like" perturbation
Kartik P. Iyer, Irene Mazzitelli, Fabio Bonaccorso +2
The effects of changing the orientation of the rotation axis on homogeneous turbulence is considered. We perform direct numerical simulations on a periodic box of grid poi…
Disentangling the triadic interactions in Navier-Stokes equations
Ganapati Sahoo, Luca Biferale
We study the role of helicity in the dynamics of energy transfer in a modified version of the Navier-Stokes equations with explicit breaking of the mirror symmetry. We select diffe…
On the evolution of particle-puffs in turbulence
Stefano Bianchi, Luca Biferale, Antonio Celani +1
We study the evolution of turbulent puffs by means of high-resolution numerical simulations. Puffs are bunches of passive particles released from an initially spherical distributio…
Phase and precession evolution in the Burgers equation
Michele Buzzicotti, Brendan P. Murray, Luca Biferale +1
We present a phenomenological study of the phase dynamics of the one-dimensional stochastically forced Burgers equation, and of the same equation under a Fourier mode reduction on…
Inverse energy cascade in nonlocal helical shellmodels of turbulence
Massimo De Pietro, Luca Biferale, Alexei A. Mailybaev
Following the exact decomposition in eigenstates of helicity for the Navier-Stokes equations in Fourier space [F. Waleffe, Phys. Fluids A 4, 350 (1992)] we introduce a modified ver…
On the Peterlin approximation for turbulent flows of polymer solutions
Dario Vincenzi, Prasad Perlekar, Luca Biferale +1
We study the impact of the Peterlin approximation on the statistics of the end-to-end separation of poly- mers in a turbulent flow. The FENE and FENE-P models are numerically integ…
Turbulence on a Fractal Fourier set
Alessandra Sabina Lanotte, Roberto Benzi, Shiva Kumar Malapaka +2
A novel investigation of the nature of intermittency in incompressible, homogeneous and isotropic turbulence is performed by a numerical study of the Navier-Stokes equations constr…
Statistical analysis of the velocity and scalar fields in reacting turbulent wall-jets
Z. Pouransari, L. Biferale, A. V. Johansson
The concept of local isotropy in a chemically reacting turbulent wall-jet flow is addressed using direct numerical simulation (DNS) data. Different DNS databases with isothermal an…
Homogeneous and Isotropic Turbulence: a short survey on recent developments
R. Benzi, L. Biferale
We present a detailed review of some of the most recent developments on Eulerian and Lagrangian turbulence in homogeneous and isotropic statistics. In particular, we review phenome…
